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.

What triangle has at least two congruent sides?

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.

A type of triangle with no equal sides?

There are three types of triangles. Scalene triangles have no congruent sides or angles, equilateral triangles have 3 congruent sides and 3 60degree angles, and isosceles triangles have two congruent sides and two congruent angles.


If two triangles have a congruent angle and two congruent sides then are the triangles guaranteed to be congruent?

Only if the congruent angle is the angle between the two congruent sides (SAS postulate).


What are three ways that you can prove that triangles are congruent?

If triangles have the corresponding sides congruent then they are congruent. SSS If two triangles have two sides and an included angle congruent then they are congruent. SAS If two triangles have two angles and an included side congruent then they are congruent. ASA SSA doesn't work.


Do equilateral triangles have at least two congrent sides?

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.


Type of triangle that has at least two sides the same?

Isosceles triangles have 2 congruent sides. Equilateral triangles have 3 congruent sides. However, all of this works only in euclidean geometry.


What postulate or theorem verifies the congruence of triangles?

sssThere are five methods for proving the congruence of triangles. In SSS, you prove that all three sides of two triangles are congruent to each other. In SAS, if two sides of the triangles and the angle between them are congruent, then the triangles are congruent. In ASA, if two angles of the triangles and the side between them are congruent, then the triangles are congruent. In AAS, if two angles and one of the non-included sides of two triangles are congruent, then the triangles are congruent. In HL, which only applies to right triangles, if the hypotenuse and one leg of the two triangles are congruent, then the triangles are congruent.


In two triangles have a congruent angle and two congruent angle and two congruent sides then the triangles are guaranteed to be congruent?

Yes, if two triangles have two congruent angles and two congruent sides then the triangles are guaranteed to be congruent. They only need two angles and one side congruent or two sides and one angle in order to be congruent.


Which type of triangles has exactly two sides that are congruent?

An Isosceles triangle has two sides (and two angles) congruent.


Are two triangles are congruent if they have the same base?

No. All corresponding sides and angles have to be congruent for the triangles to be congruent.


What is two triangles with corresponding angles and corresponding sides congruent called?

They are congruent triangles.
