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.
The statement is false. An isosceles triangle has at least two sides that are congruent, not necessarily three. A triangle with three congruent sides is called an equilateral triangle, which is a specific type of isosceles triangle.
Isosceles Triangle
A three sided closed figure. It is one of the basic shapes of geometry.
three! are you asking congruent sides? then at least 2!
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.
The least number of sides a polygon can have is three, which forms a triangle. Polygons are defined as two-dimensional shapes with straight sides, and a triangle, having three sides, is the simplest form that meets this criterion. Shapes with fewer than three sides do not enclose a space and are not classified as polygons.
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.
