Alternate Exterior Angles Example Problem

The video tutorial by Denzel Washington from tarveracademy.com explains how to solve for an angle formed by two parallel lines and a transversal. It covers the properties of angles, including equal and supplementary angles, and introduces the TBL (Tell By Looking) method for identifying angle types. The tutorial also demonstrates a mathematical approach to solving the angle equation, emphasizing the importance of verifying the final answer by substituting back into the equation.

What is the first step you should take when solving a problem involving parallel lines and a transversal?

• Immediately look for vertical angles.

• Use a calculator to find the angles.

• Attempt to solve the problem on your own first.

• Identify all right angles.

When two parallel lines are cut by a transversal, what are the possible relationships between the angles formed?

• They are either equal or add up to 360 degrees.

• They are either supplementary or complementary.

• They are either equal or add up to 180 degrees.

• They are either equal or add up to 90 degrees.

What is the easiest method to determine if angles are equal when dealing with parallel lines and a transversal?

• Use a protractor to measure each angle.

• Apply the TBL (Tell By Looking) method.

• Calculate the sine of each angle.

• Check if the angles are complementary.

In the equation 3y + 53 = 7y - 85, what is the value of y?

• 30

• 27

• 32

• 25

After finding the value of y, what should you do next to find the angle?

• Plug the value of y back into the angle expression.

• Subtract y from 180.

• Multiply y by 2.

• Divide y by 3.
