What does the term POLYGON mean?
POLY means MANY GON means ANGLES
100
Name the three types of angles we learned in the beginning of the year
Acute, Obtuse and Right
100
What is another name for a rectangle?
Square, parallelogram, quadrilateral, polygon.
100
Name two types of triangles we learned based on its SIDE LENGTHS.
Scalene, Isosceles, equilateral
100
What is the equation for the sum of interior angles of a polygon?
(n-2) x 180
200
What is another name for a rectangle and a square?
Parallelogram or quadrilateral
200
Give definitions for both an acute and an obtuse angle.
Acute: less than 90 degrees Obtuse: greater than 90 degrees
200
Fill in the blank: we can divide a rectangle into two equal _________
Triangles
200
Explain what a scalene triangle is
A scalene triangle is a triangle with no sides equal length
200
Find the area of a parallelogram that has a base of 10in and a height of 6in. SHOW YOUR WORK on your white board. ALL YOUR STEPS. EVERY SINGLE STEP!
CORRECT WORK: A = B X H A = 10 X 6 A = 60 SQ IN.
300
How many sides does a pentagon have?
5 sides because penta means five
300
What is the sum of the interior angles of a rectangle or parallelogram?
360 degrees
300
Before winter break, we looked at rectangles to calculate ________ and __________
area and perimeter
300
Explain what a isosceles triangle is
A triangle with two sides equal length
300
A rectangle and triangle have the same base and height. The rectangle has an area of 20 square centimeters. What is the area of the rectangle?
If the base and height of the triangle and rectangle are the same, then that means the triangle would fit into the rectangle. Triangles are half of rectangles, so half of 20 is 10. 10 square centimeters is the area of the triangle.
400
Draw a shape that is NOT a polygon
Student can draw a circle, oval, or any other shape that has a curve to it. Curves are not considered sides and therefore the shape cannot be a polygon
400
What is the interior sum of the angles of a triangle?
180 degrees
400
Which part of a rectangle is the area? what units do we use to show area?
The inside. We use square units
400
using your white board, draw a scalene triangle. You need to make up your own side lengths and label them. Then, draw in the height using a dotted line.
Points are given to the correct height drawn.
400
In a parallelogram, one angle is 120 degrees. What is the measure of the other angle, and how do you know?
Points are given for Correct explanation or drawing of the parallelogram with labeled angles
500
True or false: a trapezoid is a quadrilateral but NOT a parallelogram Explain your answer!
True. Because a trapezoid has 4 sides, but not all opposite sides are parallel
500
Draw an example showing complementary angles, and an example showing supplementary angles
Student drawings should have complementary angles adding to 90 degrees, and supplementary angles adding to 180 degrees
500
If a rectangle has an area of 36 square units, and a length of 3 units, what is the perimeter?
First step to take is to find the width of the rectangle. Using our equation area = l x w we plug in what we know. 36 = 3 x w since we dont know the width, we keep the w. 36 divided by 3 will give us 12. Now to find the perimeter, we add the lengths and the widths. 3 + 3 + 12 + 12 6 + 24 30. The perimeter of this rectangle is 30.
500
Come up to the board and draw an example of the "rectangle" method for finding the area of a triangle.
Points will be given to the accurate drawing and explanation of the rectangle method

You build a storm shelter with an area of 60 square feet. If one student takes up 3 square feet, how many students will you be able to shelter in the event of a severe storm?
60 divided by 3 = 20. I will be able to shelter 20 students.
