Lesson 18

A Few Angle Facts to Remember:

An Acute Angle is an angle less than 90 degrees

An Obtuse Angle is an angle greater than 90 degrees

Right Angle is 90 degrees

A straight line is 180 degrees

The 3 angles in a triangle always add up to 180 degrees

2 Angles that add up to 90 degrees are called complimentary

2 Angles that add up to 180 degrees are called supplementary
