An equilateral triangle has a perimeter of 21. What is the length of each side?
7
100
All quadrilaterals have an angle sum of ________.
360 degrees.

Can you make a polygon with side lengths of 6, 2, and 4? Why or why not?
No, 2 + 4 = 6, which is equal to 6.
100
A triangle has a right angle and a 60 degree angle. What is the missing angle measure?
30 degrees
100
What are the 3 things required for a shape to be considered a polygon?
Straight sides, closed, no overlapping sides
200
A triangle with side lengths of 7, 3, 7 is called a(n) ___________.
Isosceles triangle
200
One angle of a parallelogram measures 60 degrees and another angle measures 120 degrees. What are the measures of the other two angles? Explain.
What is 120 degrees and 60 degrees. Opposite angles in a parallelogram are always equal.
200
Can you make a polygon with the following side lengths: 10, 9, 11, 8? Why or why not?
Yes, 8 + 9 + 10 = 27, which is bigger than 11
200
A quadrilateral has angles of 47, 81, and 164. What is the missing angle?
68 degrees
200
What is the definition of a REGULAR polygon?
It is a polygon with sides AND angles that are equal.
300
The definition of a scalene triangle is____________________.
A triangle with no equal sides.
300
A quadrilateral with 4 equal sides and 4 right angles is called a __________.
Square
300
Can you make a polygon with side lengths of 32, 67, and 34?
No, 32 + 34 = 66, which is less than 67
300
A parallelogram has one angle of 42 degrees. What are the measures of the other 3 angles.
42, 138, and 138 degrees
300
How many degrees does the minute hand turn if 40 min has passed?
240 degrees
400
Triangles have an angle sum of _________.
180 degrees
400
Any polygon with 4 sides and 4 angles is called a _______________.
Quadrilateral
400
Can you make more than one triangle with side lengths of 6, 8, and 10?
No, only one triangle can ever be made from 3 given side lengths.
400
A rhombus has one angle of 112 degrees. What are the measures of the other 3 angles?
112, 68, and 68 degrees
400
A pentagon has an angle sum of ________.
540 degrees
500
If a triangle has one right angle, can it also have an obtuse angle? Why or why not?
No, the angle sum would be over 180. For example, an obtuse angle could be 100 degrees. A right angle of 90 degrees plus 100 degrees is 190 degrees - which is too big!
500
A 4-sided shape with opposite sides equal and parallel is called a ______________.
Parallelogram
500
Can you make more than one quadrilateral with side lengths of 20, 30, 20, 30? If not, why? If you can, what other shapes can you make?
Yes, you can make many different quads by changing the order of the sides or changing the size of the angles. You can make a rectangle, a kite, or many different parallelograms.
500
An isosceles triangle has one angle of 56 degrees. What are the measures of the other angles? BE CAREFUL!
There are two answers. If 56 degrees is one of the two equal angles, then the other angles are 56 degrees and 68 degrees. If 56 degrees is the angle that is NOT equal to the other two, then the other two angles are both 62 degrees.

What is the angle sum of a polygon with 9 sides?
1260 degrees
