Which equation below represents the area (
) of the rectangular picture frame shown in the description below?
Choose the correct equation:
A. A=12+8
B. A=(2X12)+(2X8)
C. A=12X8
D. 12=AX8
THE AREA CAN BE FOUND BY MULITPLYING THE LENGTH TIMES THE WIDTH SO
A=12X8
C
Which of the following figures can never have 2 pairs of parallel sides?
Select TWO correct answers.
NEITHER A TRAPEZOID OR A TRIANGLE CAN HAVE LINES OF SYMMETRY BECASUE THEY ARE MADE UP OF SLANTED LINE SEGMENTS AND CANNOT HAVE TWO SETS OF PARALLEL SIDES
Imagine a parallelogram (a four-sided shape that looks like a "slanted" rectangle). In this specific parallelogram, the top and bottom sides are parallel, and the left and right sides are parallel.
Describe the four interior angles in the parallelogram.
There are [___________] and [___________].
2 ACUTE ANGLES AND 2 OBTUSE ANGLES
Sofia is using a protractor to draw an angle that measures 115 DEGREES. First, she draws ray AB so that it points to the mark on the right side of the protractor.
To complete her 115 DEGREE angle, Sofia should draw another ray that starts at point and passes through:
Which point should Sofia use?
A Point X
B Point Y
C Point Z
D None of the above
THE ANSWER IS LETTER B. POINT Y DEMONSTRATES 115 DEGREES, BECUASE IF YOU START AT ZERO ON THE RIGHT HAND SIDE OF THE PROTRACTOR YOU WOULD BE USING THE MEASUREMENTS ON THE INSIDE OF THE SCALE TO REACH 115 DEGREES, NOT THE NUMBERS ON THE OUTSIDE OF THE SCALE. THOSE NUMBERS ARE DESIGNATED FOR RAYS POINTING TO THE LEFT.
Ms. Garcia is putting a wooden border around her rectangular vegetable garden. The garden is 18 feet long and 7 feet wide.
What is the perimeter of the vegetable garden?
50 SQUARE FEET
Maria is making a rectangular banner to hang in her classroom.
To find the area of the banner, Maria must find the:
THE ANSWER IS C
Imagine you are looking at a Square. Which of the following names can be used to describe this shape?
Select ALL that apply:
A SQUARE IS A QUADRILATERAL, A PARALLELOGRAM, A RECTANGLE, AND A RHOMBUS
A SQUARE IS NOT A TRAPEZOID BECUASE IT IS MADE UP OF TWO SETS OF PARALLEL LINE SEGMENTS
Sofia draws two lines on her whiteboard. The lines cross each other and form four perfect square corners where they meet.
Which term can be used to name what Sofia drew?
A Parallel lines
B Perpendicular lines
C Intersecting lines
D Ray lines
THE ANSWER IS B PERPENDICULAR LINES
Alex is using a protractor to draw an angle that measures 140 DEGREES. First, he draws ray XY pointing to the 0 on the right side of the protractor (using the inner scale).
To complete the 140 DEGREE angle, Alex should draw another ray that starts at point and passes through:
Which point should Alex use?
A Point G
B Point H
C Point J
D Point K
POINT H REPRESENTS 140 DEGREES BECUASE THE RAY IS POINT TO THE RIGHT SO YOU SHOULD USE THE SCALE ON THE INSIDE OF THE PROTRACTOR. THE SCALE ON THE OUTISDE THOS ENUMBERS ARE FOR RAYS THAT POINT TO THE LEFT.
Find the perimeter of a rectangular deck with the following dimensions:
THE PERIMETER IS 52 SQUARE FEET
The student council is setting up a rectangular wooden dance floor for the spring formal. They want the total area of the dance floor to be exactly 60 square feet.
If the length of the dance floor is 12 feet, what should the width be?
THE WIDTH WOULD BE 5 FT BECAUSE
A=L X W
60 = 12 X W
12X5 =60
SO THE WIDTH IS 5 FEET
Imagine a rectangular picture frame labeled ABCD.
Which statement about the line segments in this rectangle is NOT true?
STATEMENT C IS NOT CORRECT BECAUSE
AB is the same length as BC." (The top is the same length as the side). In a rectangle, the sides are usually different lengths unless it’s a square. WHICH MEANS This is NOT TRUE.
Mark draws a triangle on his paper. He uses a protractor to measure the angles and writes them down in this table:
Angle Name Angle Measure
Angle X 30 DEGREES
Angle Y 130 DEGREES
Angle Z 20 DEGREES
What type of triangle did Mark draw?
A) Acute triangle, because at least one angle is acute.
B) Obtuse triangle, because all of its angles are obtuse.
C) Obtuse triangle, because exactly one angle is obtuse.
D) Right triangle, because it has three sides.
LETTER C AN Obtuse triangle, because exactly one angle is obtuse.
ANGLE X IS 30 DEGREES AND ACUTE
ANGLE Y IS 130 DEGREES AND OBTUSE
ANGLE Z IS 20 DEGREES AND ACUTE
Angle A and Angle B are placed side-by-side to form a perfect right angle.
A. 144 DEGREES
B. 36 DEGREES
C. 46 DEGREES
D. 122 DEGREES
THE ANSWER IS 36 DEGREES
BECAUSE A RIGHT ANGLE EQUALS 90 DEGREES AND 90 - 54 = 36
Sam has 120 feet of chain-link fencing to build a rectangular dog run in his backyard. For which of these designs does Sam not have enough fencing?
OPTION D
Jenny is building a rectangular wooden deck in her backyard. The deck has an area of 80 square feet.
If the width of the deck is 8 feet, the length of the deck is:
[_________]
The perimeter of the deck is:
[_________]
THE LENGTH OF THE DECK IS 10 FEET BECAUSE A=LXW SO 80=8 X ?
8 X 10 = 80
SO THE WIDTH IS 10 FEET
THE PERIMETER WOULD BE 36
BECAUSE P=L+L+W+W OR P = 8+8+10+10
WHICH IS 36 FEET
magine a stone garden paver shaped like a trapezoid. It has a short top side, a long bottom side, and two slanted sides.
Which statement about the line segments and angles in this trapezoid is NOT true?
RESPONSE B IS NOT TRUE BECAUSE
"It has exactly 2 pairs of parallel sides." Wait! A trapezoid only has one pair of parallel sides (usually the top and bottom). If it had two pairs, it would be a parallelogram. This is NOT TRUE.
A triangle has one angle that measures 115 DEGREES and two smaller angles that are both 32.5 DEGREES.
Is the triangle an acute, obtuse, or right triangle?
Complete the sentence by filling in the blanks:
The triangle is (Blank 1) because it has (Blank 2).
THE TRIANGLE IS AN OBTUSE TRIANGLE BECAUSE EXACTLY ONE ANGLE IS AN OBTUSE ANGLE.
Angle P and Angle Q are sitting next to each other on a flat, straight line. Together, they form a straight angle.
A. 25 DEGREES
B. 115 DEGREES
C. 125 DEGREES
D. 35 DEGREES
THE ANSWER IS 115 DEGREES
BECAUSE A STRAIGHT ANGLE HAS 180 DEGREES AND
180-65 = 115
Leo has 90 feet of decorative stone border to put around a new rectangular flower bed. For which of the following garden designs does Leo not have enough stone border?
GARDEN C
Marcus is installing a rectangular swimming pool in his backyard. The pool has an area of 54 square meters.
THE WIDTH IS 9 METERS BECAUSE
A=LXW
54 = 6 X ?
54 = 6 X 9
THE PERIMETER OF THE POOL IS 30 METERS BECAUSE P = L+W+L+W
P= 9+6+9+6
P=15+15
P=30 METERS
Imagine you are looking at a blueprint for a new park. Match each "path" below to its correct geometric name: Line, Line Segment, or Ray.
Think of the "arrows" as signs that say "Keep Going!"
Maya drew a triangle where two of the sides are perpendicular to each other. This means they meet to form one 90 DEGREE angle. The other two angles are both 45 DEGREES.
Which term describes Maya’s triangle?
A Obtuse triangle, because it has more than two angles.
B Right triangle, because there is exactly one 90 DEGREE angle.
C Acute triangle, because 45 DEGREES is an acute measurement.
D Right triangle, because all three angles are 90 DEGREES.
B Right triangle, because there is exactly one 90 DEGREE angle.
Leo is measuring ANGLE RST with a protractor. He notices that neither ray is pointing at zero.
What is the measurement of ?
A) 135 DEGREES
B) 40 DEGREES
C) 95 DEGREES
D) 175 DEGREES
THE ANSWER IS C 95 DEGREES BECAUSE ANGLE RST IS MADE UP OF RAY RS AND RAY ST
SO THE DIFFERENCE BETWEEN THESE TWO NUMBERS WILL GIVE YOU THE DEGREE OF MEASUREMENT FOR ANGLE RST
SO 135-40=95
