In this article, we space going to find out what vertical angle are and how to calculate them. Prior to we begin, let’s an initial familiarize ourselves v the following concepts about lines.

You are watching: Vertical angles are supplementary true or false

What space intersecting and also parallel lines?

Intersecting lines are straight currently that satisfy or the cross each other at a particular point. The figure below shows the illustration of intersecting lines.




1400 + z = 1800

z = 1800 – 1400

z = 400

But (x + y) + z = 1800

(x + y) + 400 = 1800

x + y = 1400

900 + y = 1400

y = 500

Example 4

If 1000 and (3x + 7) ° space vertical angles, uncover the value of x.


Vertical angles space equal, therefore;

(3x + 7)0 = 100 0

3x = 100 – 7

3x = 93

x = 310

Hence, the worth of x is 31 degrees.

Applications of Vertical angles (h3)

Vertical angle have countless applications that we watch or experience in our daily lives.
