Direction: Refer to the figure and answer the following question
What type of angle pair is [math]\angle[/math]ABD and [math]\angle[/math]CBD?
Draw an angle that is complementary and supplementary to the given angle. Use the protractor in measuring. After measuring, answer the following questions being ask below.
What are complementary angles and supplementary angles?
Complementary angles are two angles that add up to equal 90.[br]Supplementary angles are two angles that add up to equal 180.
If an angle measures 34 degrees, what is the complement of the angle and the supplement of the angle?
complement of 34 degrees = 90-34 = 56 degrees[br]supplement of 34 degrees = 180-34 = 146 degrees
Find the measure of the four angles in the picture and answer the following questions being ask below.
What are angles AED and CEB called? What is so special about that type of angle?
Angles AED and CEB are called vertical angles. Vertical angles are always congruent.
What are angles AED and DEB called? What is so special about those two angles?
Angles AED and DEB are called linear pairs. Linear pairs are supplementary.
