Question

Find the area of a triangle ABC such that AB = 5cm, BC = 12 cm & CA = 13 cm ​

Answer 1

Answer:

In △ABC

(AB) 2 +(BC) 2

=(5) 2+(12) 2

=25+144=169

(AC) 2=13 2=169

AB 2+BC 2=AC 2

By converse of Pythagoras theorem

△ABC is right angle triangle, in which

∠B=90°

Step-by-step explanation:
