Vertical Angles and Linear Relationships

The video tutorial explains angle relationships, focusing on vertical and supplementary angles. It demonstrates how to determine the equality of vertical angles and solve for unknown angles using supplementary angle properties. The tutorial includes solving for X in an equation and finding specific angle measurements, such as angle le B and angle ke B, using given values and definitions.

What is the relationship between two vertical angles?

• They are complementary.

• They are equal.

• They are adjacent.

• They are supplementary.

If an angle measures 144 degrees, what is the measure of its vertical angle?

• 180 degrees

• 144 degrees

• 90 degrees

• 36 degrees

What is the sum of angles that form a straight line?

• 180 degrees

• 144 degrees

• 90 degrees

• 360 degrees

How do you find the value of X if 144 degrees plus X equals 180 degrees?

• Add 144 to both sides.

• Subtract 144 from both sides.

• Multiply both sides by 144.

• Divide both sides by 144.

What is the value of X in the equation 144 + X = 180?

• 64 degrees

• 54 degrees

• 36 degrees

• 44 degrees

What is the measure of angle le B if X is 36 degrees?

• 144 degrees

• 108 degrees

• 72 degrees

• 36 degrees

If angle Y is vertical to a 144-degree angle, what is the measure of angle Y?

• 144 degrees

• 72 degrees

• 108 degrees

• 36 degrees
