Equilateral triangles have three congruent sides and three congruent angles

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.

They have three sides and three angles

All triangles have three sides and three angles bro

The same three sides also determine the angles uniquely. However, the same three angles do not uniquely determine the sides: they only determine the ratio between the sides. So, two triangles with the same angles can be of different size (similar triangles).

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

There are three types of triangles. Equilateral triangles have three congruent sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the angles opposite those two sides are also congruent. Scalene triangles have no congruent sides or angles.

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.

No. Triangles have three angles and three sides. A quadrilateral has four angles and four sides.

If the angles of two triangles are equal the triangles are similar. AAA If you have three angles on both triangles these must be equal for the triangles to be similar. SAS If you have an angle between two sides and the length of the sides and the angle are the same on both triangles, then the triangles are similar. And SSS If you know the three sides

A triangle is a geometric figure that has three sides and three angles.

A three-sided shape is called a triangle. There are three types of triangles: equilateral triangles, iscosceles triangles, and scalene triangles. Equilateral triangles have all equal sides and angles; iscosceles triangles have two congruent legs and a base, and scalene triangles do not have any equal sides or angles.

All triangles have three sides. Hence "tri" meaning three and "angle" meaning... angle. Three angles. Three sides. All triangles have these.

There are three basic types of triangles. Equilateral triangles have three congruent (equal) sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the two angles opposite those sides are also congruent. Scalene triangles have no congruent sides or angles. Right triangles are another type of triangle and they have one ninety-degree angle. Right triangles can either be scalene or isosceles.

Equilateral triangles have that.

Yes, triangles have three angles since they have three sides.

triangles all have three sides because the stem tri means 3 and its angle means sides so it has three angles which equals three sides

no, all triangles have to have three sides and angles. :)

Equilateral triangles have three equal angles, as well as three equal sides.

Correct. Congruency means that two triangles have three pairs of congruent angles and corresponding sides of the same lengths. A pair of triangles with three pairs of congruent angles but sides of different lengths are similar, not congruent.

they all have three sides, three angles, and the sum of their angles is always 180 degrees.

All triangles have 3 sides and 3 interior angles that add up to 180 degrees

A triangle with no equal sides or angles is known as a scalene triangle. Equilateral triangles, by contrast, have three equal sides and three 60 degree angles.

The three basic types of triangles are equilateral, isosceles, and scalene. An equilateral triangle has three congruent (equal) sides and three sixty-degree angles. An isosceles triangle has two congruent sides and the two angles opposite those sides are also congruent. A scalene triangle has no congruent sides or angles.

89 well all triangles have three sides so there are three angles
