Question

Triangle ABC is a right angled at C.if AC=5 CM and BC=12 CM find its length of Ab

Answer 1

In Right triangle ABC,

Using Pythgoras Theorem

Here, AC = 5cm, BC = 12cm

AB² = AC² + BC²

AB² = 5² + 12²

AB² = 25 + 144

AB² = 169

AB = √169

AB = 13 (Root of 169 is 13)

(For a better understnading, a figure is given below)

Answer 2

We will use Pythagoras theorem
