Find the Missing Angle

The video tutorial explains how to find a missing angle in a triangle formed by intersecting lines. It covers the properties of vertical angles, supplementary angles, and the sum of angles in a triangle. By identifying congruent and supplementary angles, the tutorial demonstrates calculating the unknown angle, concluding that angle Y is 92 degrees.

What is the relationship between vertical angles?

• They are supplementary.

• They are congruent.

• They are equal to 90 degrees.

• They are complementary.

If two angles are supplementary and one is 144 degrees, what is the measure of the other angle?

• 92 degrees

• 52 degrees

• 180 degrees

• 36 degrees

What is the sum of the interior angles of a triangle?

• 90 degrees

• 180 degrees

• 270 degrees

• 360 degrees

If two angles of a triangle are 36 degrees and 52 degrees, what is the measure of the third angle?

• 72 degrees

• 180 degrees

• 92 degrees

• 88 degrees

What is the measure of angle Y if it is vertical to an angle measuring 92 degrees?

• 144 degrees

• 36 degrees

• 52 degrees

• 92 degrees
