Answer 1

A Scalene

B Isosceles

C Equilateral

Step-by-step explanation: Interior angles are all different To see why this is so, imagine two angles are the same. The triangle would then be an Isosceles triangle, which has two sides the same length. Similarly, if all three angles are the same, it would be an equilateral triangle and all three sides would be the same length.

Answer 2

1 is an isosceles
2 is scalene
3 is an equilateral
