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 if ferent ways

Answer 1

Step-by-step explanation:

Let all the angles be x(or 1x), 2x and x(or 1x).

According to question,

Sum of all the angles of a triangle is 180°.

Therefore,

X+2x+x=180°.

Or

1x+2x+1x=180°.

On Adding all the variables we get,

4x=180°

The value of x=180°/4.

Value ofall angles:-

x or 1x= 180°/4

2x=180°/4* 2=180°/2=90°.

VERIFICTION:-

To veify your anwer,add all the angles.

If the sum of all angles comes 180°, then your answer is correct and if not,

then your answer is wrong.
