What is the definition of an angle in geometry?

Back

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

Front

What are the different types of angles based on their measures?

Back

The different types of angles are acute (less than 90°), right (exactly 90°), obtuse (greater than 90° and less than 180°), straight (exactly 180°), reflex (greater than 180°), and full (exactly 360°).

Front

How do you measure an angle?

Back

An angle is measured in degrees (°) using a protractor, which aligns with one ray and allows the other ray to indicate the angle's measure.

Front

What is the sum of angles in a triangle?

Back

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

Front

What is the relationship between complementary angles?

Back

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

Front

What is the relationship between supplementary angles?

Back

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

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90°.

Front

What is an acute angle?

Back

An acute angle is an angle that measures less than 90°.

Front

What is an obtuse angle?

Back

An obtuse angle is an angle that measures greater than 90° but less than 180°.

Front

What is a straight angle?

Back

A straight angle is an angle that measures exactly 180°.
