Which set of lines best matches the ones in your question? We have some questions for you! Help us out through this
INTRO
A transversal is a line that crosses two or more lines. When the lines crossed by a transversal are parallel, we can figure out the values of all the angles formed with just one given angle. To do this, we like to imagine the set of lines as a chess board so that the colors can help us identify which angles are equal.

### angles equal to the supplementary angle of the given

In the same way that alternating squares on a chess board are the same color, alternating angles are equal.

KEY STEPS

## How to find Angles between a Transversal & Parallel Lines

### Step 1. Imagine the diagram as a chess board & identify a given angle.

You might be given more than one, but only one is needed to get started.

### Step 2. Identify all the angles that are equal to the given angle.

Equal angles make a “zig zag” along the same square color.
If you've found the unknown angle, stop 🛑. If not, keep going.

### Step 3. Find the supplementary angle of the given angle.

If you've found the unknown angle, stop 🛑. If not, keep going.

### Step 4. Identify all the angles that are equal to the supplementary angle.

Equal angles make a “zig zag” along the same square color.
