A scalene triangle is _____ an acute triangle. To be a right triangle, one of the angles has to be 90 degrees. a concave triangle… An equilateral triangle has three equal angles of 60º, so if one angle of a triangle is 90º (that is, it's a right triangle), then it cannot be an equilateral triangle. A-A right triangle is a scalene triangle. That's all we have to know. Then identify the type of figure. outside the triangle A)I only B)I or II only C)III only D)I, II, or III PLEASE HELP ME ASAP!!!!
