What are the 3 classification of triangles according to its angles?

Triangles can be classified into three types with respect to their interior angles which are: Acute-angled. Obtuse-angled. Right-angled.

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

Classifying Triangles by Sides

scalene 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 is the classification for a triangle with 3 acute angles?

acute triangle
An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°).

How many sides does a triangle 1 have?

three sides
Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs. All triangles are convex and bicentric.

How do you classify a triangle with side lengths?

Classifying Triangles by Side Lengths

An equilateral triangle has side lengths that are the same. Here is an example.
A scalene triangle is a triangle where the lengths of all three sides are different.
An isosceles triangle has two side lengths that are the same and one side length that is different.

How do you classify a triangle?

Classification of triangles based on their sides. A triangle in which all the sides are equal is called an equilateral triangle. A triangle in which any two sides are equal is called an isosceles triangle. If none of its sides are equal it is called a scalene triangle.

What type of triangle has 1 right angle?

right triangle
A right triangle will have 1 right angle and 2 acute angles. An obtuse triangle will have 1 obtuse triangle and 2 acute angles.

What is a triangle called with one right angle?

A right triangle (American English) or right-angled triangle (British), or more formally an orthogonal triangle (Ancient Greek: ὀρθόςγωνία, lit. ‘upright angle’), is a triangle in which one angle is a right angle (that is, a 90-degree angle).

What is the name of the three sides of a triangle?

The side opposite to the right angle is the hypotenuse, the longest side of the triangle. The other two sides are called the legs or catheti (singular: cathetus) of the triangle.
