Question

1)A triangle has sides that measure 3 cm, 8 cm, and 4 cm. Do these measurements form a right

triangle?
A. Yes
B. No

Answer 1

by using Pythagoras theorem,

a^2 + b^2 = c^2

LHS

3^2 +4^2

9 + 16 = 25

RHS

8^2 = 64

As both the sides of theoram aren't equal so the triangle with these measeures cant form a right angled triangle

Answer 2

A. Yes

Explanation:

the 8cm will be the hypotenuse and the 4cm and 3cm will join to create a right triangle.
