Exploring Angle Relationships and Props

This video tutorial covers angle properties, focusing on vertical, complementary, and supplementary angles. It explains how vertical angles are congruent, complementary angles add up to 90 degrees, and supplementary angles add up to 180 degrees. Each type of angle is demonstrated with examples, equations, and solutions for variables.

What are the three types of angles discussed in the video?

• Interior, Exterior, Alternate

• Parallel, Perpendicular, Skew

• Vertical, Complementary, Supplementary

• Acute, Right, Obtuse

What is the relationship between vertical angles?

• They form a straight line.

• They are congruent.

• They are always adjacent.

• They add up to 90 degrees.

If two vertical angles are given as x + 16 and 4x - 5, what is the value of x?

• 5

• 7

• 9

• 11

What is a key indicator of complementary angles in a diagram?

• Parallel lines

• Intersecting lines

• A box in the corner

• A straight line

Complementary angles add up to:

• 90 degrees

• 180 degrees

• 360 degrees

• 45 degrees

Given the angles 8x + 5 and 3x + 8 are complementary, what is the value of x?

• 8

• 7

• 6

• 5

What is the sum of supplementary angles?

• 45 degrees

• 90 degrees

• 360 degrees

• 180 degrees

If two angles are supplementary and given as 2x + 10 and x + 26, what is the value of x?

• 46

• 48

• 50

• 52

Which of the following is true about supplementary angles?

• They are congruent.

• They add up to 90 degrees.

• They are always adjacent.

• They add up to 180 degrees.
