Question

If the angles of a triangle are in the ratio 1:2:3, find all the angles of the triangle.
Classify the triangle in two different ways

Answer 1

Let the angels of triangle = 1x , 2x, 3x

then the sum of these three angles = 180°

so, 1x+2x+3x=180°

6x= 180°

x=30

so , The angels are 30°,60°,90°
