Question

In triangle abc, ab =24 cm, bc =10 cm, ac = 26 cm, is this a right triangle? Give reason for your answer​

Answer 1

In triangle abc, ab =24 cm, bc =10 cm, ac = 26 cm,

The triangle may or may not be a right angled triangle

Since it is not given that it has a 90° angle or not

And we can find if it is or not by Pythagoras theorem

Hy2=h2+b2

26x26=24x24+10x10

676=676

Hence prove

Answer 2

Answer

Because it follows Pythagoras theorem

H2=P2+B2

26x26=24x24+10x10

676=676

Hence prove
