Vertical, Complementary and Supplementary Angles

This video tutorial covers various types of angles, including vertical, complementary, supplementary, and adjacent angles. It explains how to identify these angles and solve for missing values using equations. The tutorial also provides practice problems to reinforce understanding of these concepts.

What is the main objective of the lesson on angles?

• To learn about different types of angles and solve equations.

• To draw perfect angles.

• To ignore the concept of angles.

• To memorize the names of angles.

Which of the following best describes vertical angles?

• Angles that are always acute.

• Angles that are adjacent to each other.

• Angles that add up to 90 degrees.

• Angles that are opposite each other when two lines intersect.

If two angles are vertical angles, what can be said about their measures?

• They are always different.

• They are always complementary.

• They are always equal.

• One is always twice the other.

In a diagram, if angle A is 42 degrees and is vertical to angle B, what is the measure of angle B?

• 42 degrees

• Cannot be determined

• 21 degrees

• 84 degrees

How do you solve for X if two vertical angles are given as 2X + 3 and 105 degrees?

• Multiply 2X + 3 by 105.

• Subtract 2X + 3 from 105.

• Add 2X + 3 and 105.

• Set 2X + 3 equal to 105 and solve for X.

What is the sum of complementary angles?

• 90 degrees

• 180 degrees

• 360 degrees

• 270 degrees

Which of the following pairs of angles are supplementary?

• Two angles that are adjacent.

• Two angles that add up to 90 degrees.

• Two angles that add up to 180 degrees.

• Two angles that are equal.

What defines adjacent angles?

• Angles that add up to 90 degrees.

• Angles that share a common vertex and side.

• Angles that are opposite each other.

• Angles that are always equal.

If two angles are 126 degrees and 44 degrees, are they complementary, supplementary, or neither?

• Neither

• Supplementary

• Complementary

• Both

Which of the following is true about complementary angles that are not adjacent?

• They must be supplementary.

• They can still be complementary.

• They must share a vertex.

• They cannot be complementary.
