Yes and three interior angles that add up to 180 degrees.
A triangle with two congruent sides is an isosceles triangle, and a triangle with three congruent sides is an equilateral triangle.
There is no such thing as a triangle with no sides. Every triangle must have at least three sides. The only shapes with no sides are an oval and a circle.
An EQUILATERAL triangle has all three sides the same length. An ISOSCELES triangle has two sides with the same length. A SCALENE triangle has all three sides different lengths.
Isosceles Triangle
three! are you asking congruent sides? then at least 2!
A three sided closed figure. It is one of the basic shapes of geometry.
Isosceles triangle and an equilateral triangle
Equilateral triangles have three congruent sides. That's the definition of an equilateral triangle. If it doesn't have three congruent sides, then it's not an equilateral triangle.
An isosceles triangle and an equilateral triangle
A triangle with two congruent sides is an isoscelestriangle. But an equilateral triangle has two congruent sides. (It actually has three congruent sides.) And isosceles triangle is generally described as a triangle with exactly two congruent sides.
A triangle with three sides is a polygon.
Isosceles Triangle Isosceles TriangleIsosceles triangles have at least 2 congruent sides, and equilateral triangles have all 3 sides equal. A scalene triangle has no congruent sides or angles. All triangles have 180 degrees total.An equilateral triangle has three congruent sides and an isosceles triangle has two congruent sides.
