Perpendicular
The lines that form it are perpendicular and the angle measure 90*
right angles
When lines cross they cross at a point called an intersection
Intersection
Angles that are less than a right angle less than 90*
Acute angles

obtuse Angles
Straight-line- two rays pointing in opposite directions
Straight
Two angles that form a right angle are called complementary angles
Complementary
two angles combine ti form a straight angle
