Question

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

Answer 1

Answer:

here is your answer hope this will help you

Answer 2

Answer:

Let the angles of the triangles be x,2x,x

So,  

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

x+2x+x=180

4x=180

x=45

2x=90^0

Hence the angles of the triangles are 45°,90° and 45°

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.
