Demystifying - Angle rules review

Drills

Finding angles with the point, line, parallel-line and polygon rules, and naming the reason for every step.

Author note — to cover
  • Fluency — angles at a point, on a straight line, vertically opposite and in a triangle, all whole degrees with a typed answer (4 questions).
  • Parallel lines and polygons — alternate, corresponding and co-interior angles, then interior and exterior angles of regular polygons, each paired with a single-choice reason (4 questions).
  • Catch — co-interior angles offered as equal, an isosceles triangle with two possible base angles, and an exterior angle taken from 180° instead of summing the opposite interiors (4 questions).
