How To Find X and Y with Parallel Angles -Alternate Interior Angles and Supplementary

The video tutorial explains the relationships between angles formed by parallel lines, focusing on alternate interior angles and linear pairs. It demonstrates solving for variables X and Y using these angle relationships, emphasizing the importance of understanding congruence and supplementary angles.

What is the relationship between alternate interior angles when lines are parallel?

• They are complementary.

• They are congruent.

• They are supplementary.

• They are adjacent.

If two angles form a linear pair, what is their sum?

• 360 degrees

• 180 degrees

• 45 degrees

• 90 degrees

What is the value of X if 8X - 10 = 7X?

• 15

• 10

• 5

• 20

How do you determine the value of Y using supplementary angles?

• By setting the sum of angles to 90 degrees

• By setting the sum of angles to 180 degrees

• By setting the sum of angles to 360 degrees

• By setting the sum of angles to 45 degrees

What is the value of Y if 6Y + 90 = 180?

• 20

• 15

• 25

• 10
