Quick Answer: How Do You Classify A Triangle?

What are the classifications of a triangle?

Classify triangles as acute, right, obtuse or equiangular and as scalene, isosceles or equilateral..

What do you call a triangle with 2 equal sides?

An isosceles triangle can be drawn in many different ways. It can be drawn to have two equal sides and two equal angles or with two acute angles and one obtuse angle.

What are the 7 types of triangles?

To learn about and construct the seven types of triangles that exist in the world: equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene.

What does a obtuse triangle look like?

Properties of Obtuse Triangles An obtuse triangle may be either isosceles (two equal sides and two equal angles) or scalene (no equal sides or angles). An obtuse triangle has only one inscribed square. One of the sides of this square coincides with a part of the longest side of the triangle.

How do you classify triangles by angles and sides?

Equilateral triangle. The Equilateral triangle shown on the left has three congruent sides and three congruent angles. … Isosceles triangle. The Isosceles triangle shown on the left has two equal sides and two equal angles.Scalene Triangle. The Scalene Triangle has no congruent sides. … Acute Triangle. … Obtuse Triangle.

How do you classify a triangle by its sides?

Classifying Triangles by SidesIf all the sides are equal (the same length) then the triangle is EQUILATERAL. … If 2 sides of the triangle are the same length then the triangles is an ISOSCELES triangle. … If all three sides of the triangle are a different length then the triangle is a SCALENE triangle.

How do you identify a triangle?

The following are triangle classifications based on sides:Scalene triangle: A triangle with no congruent sides.Isosceles triangle: A triangle with at least two congruent sides.Equilateral triangle: A triangle with three congruent sides.

What are 3 ways to classify a triangle by its sides?

Classifying Triangles by Sidesscalene triangle-a triangle with no congruent sides.isosceles triangle-a triangle with at least 2 congruent sides (i.e. 2 or 3 congruent sides)equilateral triangle-a triangle with exactly 3 congruent sides.NOTE: Congruent sides means that the sides have the same length or measure.

What are 2 ways to classify triangles?

An isosceles triangle has two or more equal sides, while an equilateral triangle has all three sides equal. So all equilateral triangles are isosceles. However, not all isosceles triangles are equilateral, because a triangle with only two equal sides is isosceles but not equilateral.

What are 3 attributes that describe a triangle?

Triangles are polygons with the least possible number of sides (three). The three internal angles of a triangle always add to 180 degrees. An equilateral triangle has three sides of equal length and three equal angles. An isosceles triangle has two sides of equal length and two equal angles.

What is a triangle called?

A triangle with all sides equal is called equilateral, a triangle with two sides equal is called isosceles, and a triangle with all sides a different length is called scalene.

How do you classify an isosceles triangle?

In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.
