Q: How do you prove that isosceles triangles have three equal sides?

Write your answer...

no. Equilateral triangles have all equal sides. Isoceles triangles only have 2 congruent sides. Isosceles triangles have 2 equal sides.

All of them are, isosceles triangles top 2 sides are equal. Equilateral triangles have 3 equal sides and satisfy the requirements of isosceles.

An isosceles triangles are triangles that has two sides equal. And a scalene triangles are triangles that the three sides are NOT equal.

Equilateral triangles have 3 equal sides whereas isosceles triangles have only 2 equal sides

You can't because triangles do not have diagonals but an isosceles triangle has 2 equal sides

Only an equilateral triangles have 3 equal sides whereas an isosceles triangle has only 2 equal sides.

Some people classify isosceles triangles as having at least two equal sides, while other say that they must have exactly two equal sides. So, depending on your definition, some isosceles triangles may have all equal sides, but equilateral triangles always have three equal sides.

No. Isosceles triangles have two sides of equal length.

No because an equilateral triangle has 3 equal sides but an isosceles triangle has only 2 equal sides

An isosceles triangle is a triangle that has two sides equal.

No, not at all, all isosceles triangles aren't equilateral since an equilateral triangle is a triangle with all of its sides equal, i.e. all sides of an equilateral triangle are equal, but in an isosceles triangle only two of its sides are equal.

No because although both triangles have 3 sides an isosceles triangle has 2 equal sides whereas an equilateral triangle has 3 equal sides.

No, they are not. Isosceles triangles have 2 equal sides and equilateral triangles have 3 equal sides.

Equaliateral Triangles have all three sides and angles (60 degrees)equal Isosceles Triangles have to equal sides and angles Scalene Triangles have no equal sides or angles

False. TrueAn isosceles triangle has at least 2 equal sides. An equilateral triangle has 3 equal sides. Therefore all equilateral triangles are isosceles, but not all isosceles triangles are equilateral.

Scalene triangles those triangles in which all the sides are of different lengths, but in isosceles triangles two sides of the triangle are equal in length. Therefore, no scalene triangle can ever be isosceles.

Yes. Isosceles triangles have two identical sides and angles. They are also longer than the third side.All triangles have three sides. Isosceles triangles have two sides of the same length.

No because a triangle is only an isosceles triangle when it has 2 equal sides

The length of the sides of an isosceles triangle are not set in stone. An isosceles triangle is defined as a triangle with at least two congruent sides. Equilateral triangles; that is, triangles in which all sides are of equal length are also considered to be isosceles triangles. Therefore, as long as at least two sides of the triangle are congruent, (Of equal length) said triangle is an isosceles triangle.

An isosceles triangle has 2 equal sides whereas an equlateral triangle has 3 equal sides

Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.

The definition of an isosceles triangle is a triangle with at least two sides of equal length, which means it also has two angles of equal measurement. As such, equilateral triangles; triangles in which all sides and angles are congruent (Of the same size) are also considered to be isosceles triangles.

Isosceles triangles have two equal sides. The angles opposite the equal sides are also equal. For instance, if the top angle is 48o and the two bottom angles are 66o an acute isosceles triangle is formed.

all sides equal is equilateral, two sides equal is isosceles, no equal sides is scalene.
