Unit 5 Review

Front

What is a rhombus?

Back

A rhombus is a type of quadrilateral where all four sides are of equal length, and opposite angles are equal.

Front

What is the measure of angle #2 in a rhombus if the other angles are 38 degrees?

Back

52 degrees.

Front

What is a parallelogram?

Back

A parallelogram is a quadrilateral with opposite sides that are both equal in length and parallel.

Front

If AC = 8x - 14 and EC = 2x + 11 in a parallelogram, how do you solve for x?

Back

Set the equations equal to each other: 8x - 14 = 2x + 11, then solve for x.

Front

What is the formula for the sum of interior angles of a polygon?

Back

S = (n-2) * 180, where n is the number of sides.

Front

How do you find the measure of each interior angle of a regular polygon?

Back

S = ((n-2) * 180) / n.

Front

What is the measure of each interior angle of a regular pentagon?

Back

108 degrees.

Front

What are consecutive angles in a polygon?

Back

Consecutive angles are angles that share a common side.

Front

What is the relationship between consecutive angles in a parallelogram?

Back

Consecutive angles in a parallelogram are supplementary, meaning they add up to 180 degrees.

Front

What is the measure of angle #1 if angle #2 is 117 degrees in a parallelogram?

Back

Angle #1 would be 63 degrees.
