Identify corresponding, alternate and co-interior angles when two straight lines are crossed by a transversal (ACMMG163)

LO: To identify corresponding, alternate and co-interior angle
Know:

  • That angles are created when two lines intersect each other.

Understand:

  • That angles can be classified by their location of intersection.

Do:

  • I can identify corresponding, alternate and co-interior angles

Type of Angles

Corresponding Angles – are angles on the same side of the transversal and also have the same degree of measurement.

Alternate Angles – are angles on opposite sides of the transversal. They are supplementary (both angles add up to 180 degrees). Use the Z-test to confirm alternate angles.

Co-interior Angles – are angles on the same side of the transversal and inside the parallel lines. They are supplementary (both angles add up to 180 degrees).
