100
Angles of all triangles must add up to how many degrees?
180
100
All 4 angles of quadrilaterals must equal how many degrees?
360
100
All quadrilaterals have 4 sides. True or False?
True. "Quad" means 4.
100
Parallel lines never intersect.
Correct
200
Which of the following figures is NOT a regular polygon? a. triangle b. stop sign c. parallelogram d. emerald shape
d. emerald shape
200
Triangle where all sides are the same length
Equilateral Triangle
200
How can you best describe a rhombus? a. all angles are 90 degrees b. all angles are obtuse c. adjacent sides are parallel d. opposite sides are parallel
d. Opposite sides are parallel
200
What type of quadrilateral has its top and bottom sides parallel?
Trapezoid
200
All rectangles that are cut diagonally will make two congruent triangles.
Correct
300
Which of the following is a quadrilateral? a. triangle b. hexagon c. trapezoid d. octagon
What is a trapezoid?
300
A triangle has angles that measure 50 degrees, 40 degrees, and 90 degrees. Classify this triangle by its angles. a. Acute Triangle b. Obtuse Triangle c. Right Triangle d. Equilateral Triangle
Right Triangle
300
A triangle has two equal sides. It also has two acute and one obtuse angle. What two terms apply to this triangle?
Isosceles and Obtuse
300
Which quadrilaterals have all 4 right angles?
Squares and rectangles

Mr. Pryor says that every square is a regular quadrilateral. Do you think his generalization is true?
Yes. Every square has 4 sides that are equal and 4 equal angles.
400
Compare the total number of sides in each set of shapes. Set A has 7 pentagons. Set B has 3 squares. Which has more sides Set A or Set B? Write an equation to support your answer.
Set A has 35 total sides (7x5). Set B has 12 total sides (3x4). Set A has more sides.
400
Compare and contrast an isosceles triangle and an acute triangle.
An isosceles triangle has two equal sides and can have two or three acute angles. An acute triangle can have two equal sides and has all acute angles.
400
What quadrilateral has both pairs of parallel sides and all sides are equal in length?
Parallelogram
400
Every rhombus is a parallelogram. True or False?
True
400
Which generalization can be made about trapezoids? a. A trapezoid can be a square. b. A trapezoid can be a parallelogram. c. A rectangle can be a trapezoid. d. A trapezoid has one set of parallel sides.
d. A trapezoid has one set of parallel sides.
500
When two or more shapes are the same size and all corresponding sides are the same length
What is congruent?
500
What is the difference between a scalene and isosceles triangle?
Scalene triangles have no equal sides. Isosceles triangles have two equal sides.
500
What separates a trapezoid from a parallelogram?
A trapezoid only has one set of parallel sides.
500
Compare and contrast a square and parallelogram.
Both have two pairs of parallel sides and all sides are equal. The square has all right angles.

Ms. Oliver says that a square is a rhombus because it has 4 equal sides. Ms. Jaime says that a square is a parallelogram because it has two sets of parallel sides. Who is correct?
Both are correct. A square is a parallelogram because it has 2 pairs of parallel sides. A square is also a rhombus because it has 4 equal sides.
