About This MicroSim

This interactive practice tool generates random angle relationship problems and provides step-by-step hints to help you solve them. Track your score as you practice!

Problem Types

Type Relationship Property
Complementary Two angles sum to 90° a + b = 90°
Supplementary Two angles sum to 180° a + b = 180°
Vertical Opposite angles at intersection Equal (≅)
Linear Pair Adjacent angles on a line Sum to 180°
Angle Bisector Ray divides angle in half Half of original
Corresponding Same position at parallel lines Equal (≅)
Alternate Interior Opposite sides, between lines Equal (≅)
Same-Side Interior Same side, between lines Sum to 180°
