A triangle that has one right angle is called a right triangle. A triangle that has one obtuse angle is called an obtuse triangle. When a triangle has three congruent sides, we call the triangle an equilateral triangle.Click to see full answer. Similarly, it is asked, how many congruent sides are in a right triangle?For triangles only, equiangular and equilateral have the same implications: all sides and angles are congruent. Isosceles triangles have at least two congruent sides and two congruent angles. Right triangles contain an angle whose measure is 90 degrees. All the angles in an acute triangle are less than 90 degrees.Also, which of the following best describes a triangle with one right angle and two congruent sides? isosceles triangle Also, is it possible to construct a right triangle with all sides congruent? All right triangles have two legs, which may or may not be congruent. The legs of a right triangle meet at a right angle. The other side of the triangle (that does not form any part of the right angle), is called the hypotenuse of the right triangle.What type of triangle has at least two congruent sides? isosceles triangle
