Final Exam - Segments and Angles

Front

What is the definition of a segment in geometry?

Back

A segment is a part of a line that is bounded by two distinct endpoints.

Front

What is the definition of an angle?

Back

An angle is formed by two rays (sides of the angle) that share a common endpoint (the 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 a complementary angle?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

What is a supplementary angle?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

If one angle measures 70 degrees, what is the measure of its complementary angle?

Back

The complementary angle measures 20 degrees.

Front

If two angles are supplementary and one measures 34 degrees, what is the measure of the other angle?

Back

The other angle measures 146 degrees.

Front

What is the definition of vertical angles?

Back

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

Front

What is the definition of adjacent angles?

Back

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

Front

What is the formula to find the measure of an exterior angle of a triangle?

Back

The measure of an exterior angle is equal to the sum of the measures of the two opposite interior angles.
