Are triangles equilateral?

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.


What does Isosceles Triangle and Equilateral Triangle have that is different?

Equilateral triangles have 3 equal sides, but isosceles only have two equal sides. Also, equilateral triangles have three 60° angles. Isosceles triangles have two congruent base angles and a vertex angle.


Does an isosceles triangle have two sides of equal length?

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.


How are equilateral isosceles and scalene different?

And Equilateral Triangle has three EQUAL sides. Basically just your ordinary triangle. The Isosceles triangle usually has TWO equal sides, and one odd side,( not the same size in degrees.) A scalene Triangle also has TWO of the same sides, BUT- Its degrees are usually always different. I'll show you some examples. The first example below is an isosceles Triangle. The 2nd is the Scalene Triangle... Hope I helped...


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.

What type of angles do isosceles triangles have?

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.

Does an Isosceles have two equal sides?

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.


How do you classify triangles by angles and sides?

you classify triangles by seeing the sides as if the triangle was isosceles, equilateral, or scalene Isosceles= two angles equal or two sides equal Equilateral= all angles equal and all sides equal Scalene= all angles different and all sides different. ☻☻ I HOPE IT HELPED☻☻

Are all isosceles triangles right triangles?

No, only one is and it is known as a 'right isosceles triangle'. By definition an isosceles triangle has two equal sides and two equal angles. If those two equal angles are 45o then the third angle must be 90o.


Is a triangle an isosceles triangle?

It can be, if two of the sides and two of the angles are equal. Triangles can be classified by their sides: equilateral, isosceles, scalene or by their angles: acute, right, obtuse. Combinations are possible.


Can equilateral triangles be isosceles triangles?

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