Question

3. The three angles of a triangle are in the ratio 1:2:1. Find all the angles of the triangle
Classily the triangle in two different ways.​

Answer 1

Step-by-step explanation:

Let the angles of the triangles be

So,

As we know the sum of internal angles of a triangle is 180. so,

Hence the angles of the triangles are

.

On the Basis of sides, the triangle is isosceles triangle as two sides of the triangle are equal.

On the Basis of angle, the triangle is Right-Angled Triangle as it has one angle equal to 90 degrees.

Answer 2

ANSWER:

x+2x+x=180°

4x=180°

x=45°

first and third angles are 45 degrees and the second is 90 degrees
