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

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

∠cbe and ∠deb are same-side interior angles.
