Question

abc is a triangle such that ab=5cm , bc=12cm , ac=13cm. if d is the middle 9f ac , then bd is equal to​

Answer 1

Step-by-step explanation:

In △ABC,

(AB) ²+(BC) ²=(5) ²+(12) ²

=25+144=169 = 13²

=(AC)²

⟹AC=13

The converse of the Pythagoras theorem states that if the square of the longer side of a triangle is equivalent to the sum of its two shorter sides, then it must be a right triangle.

∴ △ABC is right angle triangle, in which ∠B=90°
