Hi,
Angle 1. From what I have learnt, Angle 4= Angle 1 and their angle property is known as the vertically opposite angles :)
Hope this helps :)

Angle 1. Because angle 4 and 1 are vertical angles and vertical angles are congruent.

Does 10,15,20 form a right triangle

sveta [45]

A right triangle can only be formed when you use the 3/4/5 rule.
The 3/4/5 rule is a^2 + b^2 = c^2.

We will use 10 for a, 15 for b, and 20 for c.

a^2 + b^2 = c^2

Plug in 10 for a, 15 for b, and 20 for c.

10^2 + 15^2 = 20^2

10^2 = 100

15^2 = 225

20^2 = 400

100 + 225 = 400
This is not applicable, as 100 + 225 = 325.

Your answer is:

No, 10,15,20 does not form a right triangle.

I hope this helps!
