Front

If m∠AOB = 32° and m∠BOC = 17°, find m∠AOC.

Back

m∠AOC = m∠AOB + m∠BOC = 32° + 17° = 49°.

Front

What is the midpoint between (3, -1) and (7, -5)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2) = ((3 + 7)/2, (-1 - 5)/2) = (5, -3).

Front

What is the measurement of angle BAL?

Back

m∠BAL = 110 degrees.

Front

Back

Segment is a part of a line that is bounded by two distinct end points.

Front

What is the definition of complementary angles?

Back

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

Front

What is the definition of supplementary angles?

Back

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

Front

What is the formula for finding the distance between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What is the definition of vertical angles?

Back

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

Front

What is the definition of a line segment?

Back

A line segment is a part of a line that has two endpoints.
