Question

A triangle has sides with lengths of 5 centimeters, 12 centimeters, and 14 centimeters. Is it a right triangle?

Answer 1

Answer:

no

Step-by-step explanation:

You use the Pythagorean Therom and square your legs (5 and 12) and your hypotenuse (14) it would add up to 25+144=196.

This is not true since 144+25 is 169, not 196

Answer 2

Answer:

Nope

Step-by-step explanation:

Hypotenuse = 14

Use Pythagoras' Thereom:

\sqrt{12^2+5^2}=13

The equation did not equal the hypotenuse, therefore it is not a right-angled triangle.
