Question

if the 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

LET ,

The sum of angles is 180

hence,

sum of ratio=180

1x+2x+1x=180

4x=180

x=45

hence first and third angle =45

and second angle=2*45=90

classification:

one of the angles of triangle is 90 hence that triangle is right angled triangle

and two angles are same then that triangle is isoscales triangle
