There are three ways to classify a triangle by its sides:
A scalene triangle is a triangle where no two sides are of the same length. That is, all three sides are different lengths
An isosceles triangle is a triangle where at least two sides have equal length. (Note: In some textbooks, they define an isosceles as having exactly two sides with equal length).
An equilateral triangle has all three sides with equal lengths. By the first definition for isosceles, this means that an equilateral triangle would also be isosceles. It all depends on the book being used.
What else can I help you with?
How can triangles be classified?
sides, and angles
Which triangle is classified by their congruent sides?
Equilateral, Isosceles and Scalene are three types of triangles classified based on how many congruent sides the triangle has.
What are the shapes that have 3 sides and 3 vertices?
The shapes that have 3 sides and 3 vertices are called triangles. Triangles are classified based on the lengths of their sides and the measures of their angles. The three most common types of triangles are equilateral triangles (all sides and angles are equal), isosceles triangles (two sides and two angles are equal), and scalene triangles (all sides and angles are different).
What is anther types of a triangles?
Triangles can be classified by their sides: equilateral, isosceles, scalene or by their angles: acute, right, obtuse. Combinations are possible.
Can a triangle have 2 parallel sides?
Nope, never. Parallelograms are classified as having 1 or 2 sets of parallel sides, not triangles.
What are the different kind of triangles?
there is the Equilateral Triangle which all sides are equal.there is the Isosceles Triangle where only two sides are equal.there is the Scalene Triangle where no sides are equal.can help you:http://www.easycalculation.com/trigonometry/triangles-sides.php
What triangle has 6 sides?
A triangle by definition has three sides, so a shape with six sides cannot be a triangle. A shape with six sides would be classified as a hexagon. Triangles are specifically defined as polygons with three sides and three angles.
Classification of triangle according to sides?
Oh, dude, you're talking about triangles now? Alright, so, like, triangles can be classified based on their sides - you've got equilateral triangles (all sides are equal), isosceles triangles (two sides are equal), and scalene triangles (all sides are different lengths). It's like a little triangle party with different sides showing up!
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.
Are there triangles with 4 sides?
No. Triangles all have three sides.
How many triangles are in a square?
There are no triangles in a square. A triangle is a 3 sided figure. A square is a 4 sided figured classified as quadrilateral meaning it has 4 sides. A triangle can be any size, as long as it has 3 sides. A quadrilateral can also be any size it just has to have 4 sides as well.
How many sides does a triangular pryimed have that are triangles?
it has 4 sides that are triangles
