They can make accurate estimates by looking at an angle and understanding where about where others are. Example if you needed to guess where 40 degrees is you sketch a 90 angle and cut in half and that is 45 degrees so that is close.
Fundus angles are benchmark angle
45
Supplementary angles are 2 angles whose measures = 180o.
Two angles are complementary if the sum of their measures is 90 degrees.Two angles are supplementary if the sum of their measures is 180 degrees.
SUPPLEMENTARY ANGLES are two angles the sum of whose measures is 180 degrees.
Fundus angles are benchmark angle
um is it 60
45
Acute angles are greater than 0 but less than 90 degrees
A protractor measures the degree of angles and circles.

Measures of what? The interior angles, the exterior angles, the lengths of sides?
