Year 7 Geometry Revision

What is a Co-Interior Angle?

• An angle that creates an F shape, with one angle outside the parallel lines and one on the inside. Angles are equal.

• An angle that creates a C shape with both angles inside the parallel lines. It also adds up to 180∘

• An angle that creates a Z shape, with both angles inside the parallel lines. Angles are equal.

• When two lines intersect, the opposite X angles are equal.
