How to Find Vertical Angles? (+FREE Worksheet!)
Angle\(1\)+ Angle\(3\)=\(180\)(because it is a straight angle) Angle\(2\)+ Angle\(3\)=\(180\)(because it is a straight angle) Angle \(1\) and angle \(2\) are vertical angles. Angle \(3\) and angle \(4\) are vertical angles. Angle \(1\) and angle \(3\) are NOT vertical angles. Finding Vertical Angles Example 1: Solution: \((3x+50)^{\circ}\) and \((5x+10)^{\circ}\) are vertical angles. \(3x+50=5x+10→3x+50-50=5x+10-50→3x=5x-40→3x-5x=-40→-2x=-40→x=20\) \((3x+50)^{\circ}=(3(20)+50)=110^{\circ}\) \((5x+10)^{\circ}=(5(20)+10=110^{\circ}\) Finding Vertical Angles Example 2: Find the number […]
