acute triangle, acute-angled triangle-a triangle whose interior angles are all acute. equiangular triangle, equilateral triangle-a three-sided regular polygon. isosceles triangle-a triangle with two equal sides. oblique triangle-a triangle that contains no right angle.
A right triangle is a triangle where one of the angles is 90Âº. A right triangle cannot be an equilateral triangle because all of the angles in an equilateral triangle are 60Âº. There are also two other designations of triangles, acute and obtuse. Acute triangles are triangles where all three angles are less than 90Âº.
