Unit 1 Geometry Test

Front

What are complementary angles?

Back

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

Front

If m∠K = (3x + 3)° and m∠L = (10x - 4)°, how do you find the measures of angles K and L?

Back

Set up the equation (3x + 3) + (10x - 4) = 90, solve for x, then substitute back to find m∠K and m∠L.

Front

What is the supplement of a 50˚ angle?

Back

The supplement of a 50˚ angle is 130˚.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What does it mean for points to be collinear?

Back

Collinear points are points that lie on the same straight line.

Front

What is the sum of the measures of angles in a triangle?

Back

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

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal.

Front

How do you determine if two angles are supplementary?

Back

Two angles are supplementary if their measures add up to 180 degrees.

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.
