Teach it

Where it is taught, with guided notes, practice, homework, an exit ticket and an interactive Teacher Deck.

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.
