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
