**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**

**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).
