Home » Aptitude » Plane Geometry » Question

If the sides of a triangle are in the ratio 3 : 1 1 : 3 1 then the traigle is
4 4

Here , Ratio of sides = 3 :	5	:	13
	4		4

Ratio of sides = 12 : 5 : 13
∴ 5² + 12² = 13²
From above relation it is clear that It is a right angled triangle .

If the sides of a triangle are in the ratio 3 : 1	1	: 3	1	then the traigle is
	4		4
