## How do you classify a triangle by its sides?

When classifying a triangle by its sides, you should look to see if any of the sides are the same length. If no sides are the same length, then it is a scalene triangle. If two sides are the same length, then it is an isosceles triangle. If all three sides are the same length, then it is an equilateral triangle.

## How do you classify a triangle with 3 sides?

Classifying Triangles by Side Lengths

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

How do you classify a triangle by both sides and angles?

Acute angle: An angle with a measure less than 90 degrees. Equilateral triangle: A triangle with three sides of equal length. Isosceles triangle: A triangle with at least two sides of equal length. Line of symmetry: A line through a figure that creates two halves that match exactly.

### What are two ways to classify triangles?

Triangles can be classified either according to their sides or according to their angles. All of each may be of different or the same sizes; any two sides or angles may be of the same size; there may be one distinctive angle.

### How do you classify a triangle?

Is a 3 sided shape always a triangle?

A three-sided polygon is a triangle. There are several different types of triangle (see diagram), including: Equilateral – all the sides are equal lengths, and all the internal angles are 60°. Isosceles – has two equal sides, with the third one a different length.

#### How do you classify triangles?

Triangles can be classified by their sides and by their angles. When classifying a triangle by its sides, you should look to see if any of the sides are the same length. If no sides are the same length, then it is a scalene triangle. If two sides are the same length, then it is an isosceles triangle.

#### How many ways can you classify a triangle?

There are two ways to classify triangles. To classify a triangle by angles means to categorize the triangle according to the types of angles that make up the triangle. To classify triangles by angles you must determine if each angle in the triangle is acute, right or obtuse.

What are two ways to classify Triangles?

## What shape has 3 more sides than a triangle?

Polygons: How Many Sides?

3 triangle, trigon
7 heptagon
8 octagon
9 nonagon, enneagon
10 decagon

## How can triangles be classified by their sides?

The types of triangles classified by their sides are the following: Equilateral triangle: A triangle with all three sides equal in measure. In Figure 1, the slash marks indicate equal measure. Isosceles triangle: A triangle in which at least two sides have equal measure (Figure 2).

What are the different ways to classify triangles?

Obtuse Triangle: A triangle with one obtuse angle.

• Acute Triangle: A triangle where all three angles are acute.
• Equiangular Triangle: A triangle where all the angles are congruent.
• Scalene Triangle: A triangle where all three sides are different lengths.
• Isosceles Triangle: A triangle with at least two congruent sides.
• ### How do you determine the sides of a triangle?

According to the Law of Sines, the ratio of the sines of each angle divided by the length of the opposite side are all equal. This helps you to find the sides of the triangle.

### How do you classify triangles sides?

Method 1 of 2: Classify Triangles by Sides Measure each side of the 3 sides of the triangle using a ruler. Place the ruler at the end of each line segment of the 3 lines in the triangle and measure to the opposite endpoint of each line. Make note of the measurement for each of the 3 triangle sides. Determine how the 3 sides compare in length.

How do you classify a triangle by its sides? When classifying a triangle by its sides, you should look to see if any of the sides are the same length. If no sides are the same length, then it is a scalene triangle. If two sides are the same length, then it is an isosceles…
