Using Alternative Exterior Angles to Find the Value of X

The video tutorial covers various angle relationships in geometry, focusing on alternate interior, consecutive interior, alternate exterior, and corresponding angles. It explains how these angles relate to parallel lines and transversals, emphasizing that consecutive interior angles sum to 180 degrees, while others are equal. The tutorial also demonstrates solving equations using these angle relationships, providing a step-by-step approach to finding the value of variables. Finally, it offers guidance on applying these concepts to homework problems.

Which of the following angle relationships add up to 180 degrees?

• Alternate interior angles

• Consecutive interior angles

• Alternate exterior angles

• Corresponding angles

What is the position of exterior angles in relation to parallel lines?

• Outside the parallel lines

• Between the parallel lines

• On the same side of the transversal

• Inside the parallel lines

Alternate exterior angles are:

• Equal to consecutive interior angles

• Always different

• Equal to 180 degrees

• Equal to each other

When solving for X using alternate exterior angles, what is the first step?

• Multiply the angles

• Subtract the angles

• Set the angles equal to each other

• Add the angles together

What should you do if you have variables on both sides of an equation?

• Divide them

• Ignore one side

• Subtract one from the other

• Add them together
