How many sides and corners are in a triangle?
A triangles has three sides (also known as edges) and three corners (also known as vertices).
Are there triangles with 4 sides?
No. Triangles all have three sides.
If three corresponding sides of one triangle are proportional to three sides of another then the triangles are similar?
Yes, if the three corresponding sides of one triangle are proportional to the three sides of another triangle, then the triangles are similar. This is known as the Side-Side-Side (SSS) similarity criterion. When the sides are in proportion, it ensures that the angles of the triangles are also equal, thus confirming their similarity. Similar triangles maintain the same shape but may differ in size.
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.
Quadrilaterals are polygons that have three sides?
Quadrilaterals are polygons with four sides. Triangles are polygons with three sides.

Does a scalene triangle have three sides?
All triangles have three sides. Hence "tri" meaning three and "angle" meaning... angle. Three angles. Three sides. All triangles have these.
Quadrilaterals are polygons that have three sides?
Quadrilaterals are polygons with four sides. Triangles are polygons with three sides.
What shape has three sides?
Triangles have three straight sides.
What shape has three different sized sides?
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.
How many congruent sides and angles do equilateral triangles have?
Equilateral triangles have three congruent sides and three congruent angles
Why do all triangles have 3 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
What are the properties of the different types of triangle?
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.
What are the three kinds of triangles according to the no of sides?
All triangles have exactly three sides. If the number of sides were anything other than three there would not be a triangle - of any kind.
