Maths – Angles with Parallel Lines

Posted on: July 1, 2016

A good video to clarify the angle names when a transversal intersects two or more lines, and why in the exam, we must not miss out specifying the angles are on parallel lines.

同位角 corresponding angles – 相等 equal

内错角 alternate interior angles – 相等 equal

同旁内角consecutive interior angles / interior angles on the same side of transversal – 互补 supplementary

And the below is another good site to learn more about angles on parallel lines:
