Question

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

Answer 1

Answer:

45°,90°,45°

Step-by-step explanation:

Let the angles be x ,2x ,x

∴ x + 2x + x =180°

∴ x = 45°

2x = 90°

Angles are 45°,90°,45°

So the triangle is a right angled triangle with two sides same...

Answer 2

Let angles be x, x and 2x
According to traingle sum law:
Sum of three angles is 180 degree
x + x +2x=180
4x=180
X=180/4=45
The angles are:
X=45
X=45
2x= 45 (2)=90
The triangle is a right angle triangle and isosceles triangle.
