Question

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

Answer 1

Step-by-step explanation:

Let ABC be the D

Let ∠A=x

∠B=2x

∠C=x

∠A+∠B+∠C=180

4x=180

x=45

∠A=45

∠B=90

∠C=45

Since ∠A=∠C

ABC is isosceles D

4

.

Since ∠B=90

ABC is Right angled at B.
