CCGPS Geometry 5 - Congruence & Triangles 5.1 – Practice Name: ________________________________________________ Date: _______________________ Vertical Angles and Linear Pairs If two angles share a vertex and together they make a straight angle, then the two angles are called a linear pair. Practice Problems: Find the missing angle. 1) 2) 3) 60ᵒ Solve for x. 4) 155ᵒ 35ᵒ 5) x + 30 2x 2x + 10 70ᵒ 6) Linear pairs could be defined as being supplementary angles because they always add up to 180º. Are all supplementary angles linear pairs? Explain. Practice Problems: Solve for the variable(s). 1) 2) xᵒ 130 yᵒ ᵒ zᵒ 3) (2x – 17)ᵒ 122ᵒ 4) (x – 12)ᵒ 5) (119 – x)ᵒ (x + 135)ᵒ 105ᵒ (2x + 5)ᵒ (3x + 11)ᵒ
