You can classify a triangle by its sides, or by its angles.
To classify a triangle by its sides:
1- A triangle with three sides that are equal in length is called an equilateral triangle.
2- A triangle with two sides of the same length and one different is called an isosceles triangle. 3- A triangle with no sides of equal length is called a scalene triangle. To classify a triangle by its angles: 1- A triangle with three angles that are greater than 0 and less than 90 degrees is called an acute triangle.
2- A triangle with one angle that is 90 degrees exactly is called a right angle triangle.
3- A triangle with one angle that is greater than 90 degrees is called an obtuse triangle.

How can triangles be classified by their sides?
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 lengthsAn 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 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
A triangle that has angles that measures 454590 degree is a?
A 45-45-90degree triangle is classified as an isosceles triangle.
How do you Compare and contrast an isosceles triangle and an acute triangle?
First, figure out what ways they are similar. Then, figure out what ways they are different. For example, they are both triangles, but iscoceles has 4 syllables, while acute only has two.
What type of triangle has an angle that measures 20 and an angle that measures 90?
Any triangle with a 90 degree angle is classified as a right triangle.
