Question

LMN is a right triangle. True or False

Answer 1

False

Explanation:

Let us check using Pythagorean Theorem

`c^2 = a^2 + b^2`

Where c is the hypotenuse (14), a is the base (13) and b is the perpendicular (5)

Putting in the above formula

`14^2 = 13^2 + 5^2`

196 = 169+25

196 ≠ 194

So, It is not a right angled triangle
