Geometry Exam Review 1

Front

What are vertical angles?

Back

Vertical angles are angles that are opposite each other when two lines intersect. They are always congruent (equal measures).

Front

What is the measure of angle 1 if it is 113 degrees?

Back

m∠1 = 113 degrees.

Front

If KL = 6, what does this represent in geometry?

Back

KL represents the length of a line segment in geometry.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is a rotation in geometry?

Back

A rotation is a circular movement of a figure around a fixed point.

Front

What is the relationship between complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

Define adjacent angles.

Back

Adjacent angles are two angles that share a common side and a common vertex.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

What is the difference between a translation and a reflection?

Back

A translation moves a shape without rotating or flipping it, while a reflection flips a shape over a line.

Front

What is the formula for finding the area of a rectangle?

Back

Area = length × width.
