Rotate the protractor around to help you solve the first 5 questions. List the first five answers here ______ _____ ______ ______ ______ Now go to http://www.southallegheny.org/webpages/trishel/geometry.cfm?subpage=896155 Or Google “Pairs of Angles Applet” and select the webpage that lists the matching web address above 1) Adjacent Angles: Select the Adjacent Angles “Click Here”. Draw a pair of adjacent angles below. 2) Can the adjacent angles overlap? 3) Vertical Angles: Select the Vertical Angles “Click Here”. Draw and identify a pair of vertical angles below. Complete the sentence: Notice in the applet the vertical angles are always ___________ In the picture to the right… 4) Which two angles are adjacent? __________ 5) Which two angles are vertical angles?______ 6) Complementary Angles: Select the Complementary Angles “Click Here”. Draw a pair of complementary angles below. (In the applet keep angle PQR acute to keep them complementary). 7) Complementary angles always add up to _____. 8) Do complementary angles have to be adjacent (share a side)? _____ 9) If angle ABC = 3x, angle DEF = 6x, and the two angles are complementary, write an equation to find x and then solve for x. 10) Supplementary Angles: Select the Supplementary Angles “Click Here”. Draw a pair of supplementary angles below. 11) Supplementary angles always add up to _____. 12) Do supplementary angles have to be adjacent (share a side)? _____ 13) If angle ABC = 3x, angle DEF = 5x + 20, and the two angles are supplementary, write an equation to find x and then solve for x. 14) Linear Pair of Angles: Select the Linear Pair of Angles “Click Here”.
