Corresponding

8.G.A.5

Definition

Angles in matching positions where a transversal crosses two lines. When the lines are parallel, corresponding angles are equal.

Examples

  • If one corresponding angle is 110°, the other is also 110°.
  • They sit in the same position at each crossing, like top-right and top-right.

Key rule

Parallel lines make corresponding angles equal.

Memory hook

Same position, each intersection, equal angles.
