Using corresponding angles to show two lines are parallel - Free Math tutorial

The video tutorial explains how to determine if two lines are parallel by examining same side interior angles. If these angles are equal, the lines are parallel. The instructor demonstrates setting up an equation to find the value of X that makes the angles equal, thus confirming the lines are parallel when X equals 1.2.

What is the theorem that helps determine if two lines are parallel by examining angles?

• Corresponding Angles Theorem

• Vertical Angles Theorem

• Alternate Interior Angles Theorem

• Same Side Interior Angles Theorem

What is the first step in setting up the equation to find the value of X?

• Add the angles together

• Multiply the angles

• Set the angles equal to each other

• Subtract the angles

What operation is performed after setting the angles equal to each other in the equation?

• Subtract 3X from both sides

• Add 3X to both sides

• Divide both sides by 3

• Multiply both sides by 3

What is the value of X that makes the two lines parallel?

• 2.0

• 1.2

• 1.5

• 1.0

When the value of X is found, what does it indicate about the angles?

• The angles are equal

• The angles are supplementary

• The angles are different

• The angles are complementary
