Question

if the side of a triangle are in the ratio 3:4:5,prove that it is right angle triangle
​

Answer 1

Step-by-step explanation:

if the side of a triangle are in the ratio 3:4:5

Then,let the sides be 3x,4x and 5x

Now, 3x)^2 + (4x)^2 = (5x)^2

Pythagoras theorem- P^2 + B^2 =H^2

Pythagoras theorem is valid for this triangle.

Hence, it is a right angled triangle.

Answer 2

Step-by-step explanation:

let the sides of the triangle be x .

then , sides of the triangle = 3x , 4x and 5x .

(3x)^2 + (4x)^2 = (5x)^2

the Pythagoras theorem is valid here

so , it is a right angle triangle .
