No right triangle can have any obtuse angles inside it.
Two. Two acute angles in a right triangle.
angles that measure 90 degrees.
Equilateral Triangles do not contain right angles, since all angles in this shape are equal and it is impossible to make a triangle that consists of three 90 degress angles. Isosceles and Scalene may contain a right angle.
90 degrees
If it has no right angles, it is not a right triangle and therefore you cannot name a hypotenuse of that triangle. Which implies you cannot find that side's measure.
Is a right angled triangle.
