Step1: Define right triangle

A right triangle has one 90° angle. Triangles B and C have a visible right angle, while A and D do not.

A scalene triangle has all sides of different lengths, so no equal sides/angles. Triangle B appears to have two equal sides (isosceles right triangle), while triangle C has all sides of distinct lengths.
