What is a triangle in math?

A triangle has three sides, three angles and three vertices.
Sum of all three interior angles of a triangle is 180°.
Sum of the length of two sides of the triangle is greater than its third side.

Which figures are triangles?

In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices.
The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees.
This property is called angle sum property of triangle.

What are the 7 types of triangles?

The six types of triangles are: isosceles, equilateral, scalene, obtuse, acute, and right.
An isosceles triangle is a triangle with two congruent sides and one unique side and angle.

A triangle is a polygon with three corners and three sides, one of the basic shapes in geometry. The corners, also called vertices, are zero-dimensional points while the sides connecting them, also called edges, are one-dimensional line segments. The triangle's interior is a two-dimensional region.

Exterior Angles

For a triangle, an exterior angle is an angle formed by one side of the triangle and a line extended from another of its sides. The measure of an exterior angle of a triangle equals the sum of its two remote interior angles. For ?ABC shown above, ?CAD is the exterior angle for ?A and ?B and ?C are the two remote interior angles. We know that ?CAB +...

Equilateral, Isosceles and Scalene

A triangle can only be formed when the sum of any two sides of the triangle is greater than its third side. If one side of a triangle is longer than another side, the angle opposite the longer side must be greater than the angle opposite the smaller side. This is true for any triangle. As an example, you can see from the side and angle measures giv...

There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or noequal sides/angles: How to remember?Alphabetically they go 3, 2, none: 1. Equilateral: "equal"-lateral (lateral means side) so they have all equal sides 2. Isosceles: means "equal legs", and we have two legs, right? Also iSOSceles...

Properties of A Triangle

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon. The above figure is a triangle denoted as ?ABC. Examples of Triangles Some real-life examples of triangles include sandwiches, traffic signs, cloth hangers, and a rack in billiards. Non-examples of Triangles The above figures are non-ex...

Types of Triangles

A triangle has 3 sides. In triangle ABC, the sides are AB, BC, and CA.

Solved Examples

The sum of all three interior angles of a triangle is always equal to 180?.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon. The above figure is a triangle denoted as ?ABC.

What are the 7 types of triangles?

In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle.

How many sides does a triangle have?

A triangle has three sides and three angles The three angles always add to 180° Equilateral, Isosceles and Scalene There are three special names given to triangles that tell how many sides (or angles) are equal.

What are the 3 types of triangles?

Equilateral, Isosceles and Scalene. There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or no equal sides/angles:

What is the shape of a triangle?

In geometry, a triangle is a closed, two-dimensional shape with three straight sides. A triangle is also a polygon . Classify triangles based on side lengths and angle measures. Look for acute, obtuse and right angles and identify equal sides. We can find the shape of a triangle in a flag, the musical instrument triangle, and a roadside signboard.

How to classify triangles according to their angles?

To classify triangles according to their angles, we measure each of their interior angles. Triangles can be classified by angles, as: To classify triangles according to both angles and sides, we measure the interior angles and length of the sides of the triangle. Triangles classified based on both angles and sides are –

The two basic triangle formulas are the area of a triangle and the perimeter of a triangle. These triangle formulas can be mathematically expressed as; Area of triangle, A = [ (½) b × h]; where 'b' is the base of the triangle and 'h' is the height of the triangle.
