Overview of Right Triangles
Which of the following types of triangles can also be a right triangle?
Indicate __all__ such types.
Correct!
For example, you could have the following 30°-60°-90° right triangle that is scalene (no equal sides):
Correct!
Consider the following 45º-45º-90º isosceles triangle (two equal sides):
Incorrect.
Note that an equilateral triangle has three equal sides and also three equal angles. Since the sum of the three angles must be 180º, each angle must measure 60º. Hence, there cannot be any angle that measures 90º.
Thus, a right triangle cannot be equilateral.

Isosceles
