Given:

The angles of a triangle are in the ratio 1 : 2 : 3.

Concept:

The sum of the angles in any triangle is 180°.

Calculation:

Let the angles be x, 2x, and 3x.

⇒ x + 2x + 3x = 180°

⇒ 6x = 180°

⇒ x = 30°

So, the angles are 30°, 60°, and 90°.

In a triangle with angles 30°, 60°, and 90°, the sides are in the ratio 1 : √3 : 2.

∴ The ratio of the corresponding sides is 1 : √3 : 2.
