Question

ratio of the lenght of three sided ofva triangle is 5:12:13. then show that the triangle is always right angled​

Answer 1

Answer:

Since ratio is 5:12:13 and if each side is x times then the length will be 5x, 12x and 13x.

Now (13x)²=(5x)²+(12x)² [ since 169=25+144]

In right angled triangle hypotenuse²=base²+perpendicular².

Hence it is always right angled triangle.
