Question

The angles of a triangle are in the ratio 1:2:3, then the triangle is-
किसी त्रिभुज के कोणों का अनुपात 1 : 2 : 3 है। तब वह त्रिभुज है-​

Answer 1

Step-by-step explanation:

The angles of a triangle are in the ratio 1:2:3 ----- ( given )

Let 1:2:3 be 1x, 2x and 3x.

Sum of measures of angles of a triangle is 180°.

1x + 2x + 3x = 180°

6x = 180°

x = 180/6

x = 30°

Measures of three angles -

1x = 1 × 30 = 30°

2x = 2 × 30 = 60°

3x = 3 × 30 = 90°

Hence, it is a right - angled triangle.
