Angle Problem Solver
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° |
