Math 7/8 More Work with Complementary and Supplementary Angles 2016 Name ___________________________ February 23, 2016 Review of Main Ideas with Angles so far: Two angles are complementary angles if the sum of the measures is __________. Two angles are supplementary angles if the sum of the measures is __________. All straight lines have a sum of _______________. All triangles have a sum of _____________. Vertical angles are opposite angles formed by the intersection of two lines. Vertical angles are ____________. In a triangle, the measure of an exterior angles is equal to the sum of the two remote _____________ angles. In any triangle, the sum of any two sides must be ______________ greater than the third side. Warm-Upβ Questions Find the value of x in each figure below: 1) 3) 2) 4) We can use what we know about angles above in combinations to find the missing angles of more complicated problems. Example 1: If mβ πΎπΊπ½ = 25, find the πβ πΎπΊπΆ = _______________. If mβ πΎπΊπ½ = 25, find the πβ π·πΊπΈ = _______________. If mβ πΎπΊπ½ = 25, find the πβ π½πΌπ» = _______________. If mβ πΎπΊπ½ = 25, find the πβ πΌπ½πΎ = _______________. Example 2: Example 3: Guided Practice: 1) Hmwk p. 731 β 732 (4, 5, 6, 7, 12, 13, 14) 2)
