What is Triangle explain?

A triangle is a polygon with three edges and three vertices.

It is one of the basic shapes in geometry.

A triangle with vertices A, B, and C is denoted .

In Euclidean geometry any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e.

a two-dimensional Euclidean space)..

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.

How do you find area?

To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.

What is the best definition of a triangle?

A triangle is a three-sided polygon that closes in a space. It uses lines, line segments or rays (in any combination) to form the three sides. When three sides form and meet, they create three vertices, or corners. The corners inside the triangle are interior angles.

What is triangle and types of triangle?

Triangles are shapes with three sides. … A triangle’s type depends on the length of its sides and the size of its angles (corners). There are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene. The green lines mark the sides of equal (the same) length.

What makes up a triangle?

A triangle is composed of three line segments. … A triangle is classified by its angles and by the number of congruent sides. A triangle that has three acute angels is called an acute triangle. A triangle that has one right angle is called a right triangle.

What is a real life example of a triangle?

Traffic Signs. Traffic signs form the most commonly found examples of the triangle in our everyday life. The signs are in equilateral triangular shape; which means that all three sides are of equal lengths and have equal angles.

What is meant by equilateral triangle?

In geometry, an equilateral triangle is a triangle in which all three sides are equal. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

What are the 4 types of triangle?

There are a number of different types of triangles, such as equilateral triangles, right triangles, scalene triangles, obtuse triangles, acute triangles, and isosceles triangles.

How can we find area of triangle?

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles.
