Quick Answer: What Are The Types Of Triangles According To Sides?

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)..

Which is 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.

Can triangles have curved sides?

There are two ways I triangle can have curved sides—in one case the sides curve in, and in the other the sides curve out. In the first case, the triangle is called “hyperbolic”—see Hyperbolic triangle —and in the the second, the triangle is called “spherical”—see Spherical geometry .

What is a 3 sided triangle called?

equilateral triangleAn equilateral triangle has all the three sides equal and all three interior angles equal too. In this case, each interior angle of an equilateral triangle is 60 degrees. An equilateral triangle is sometimes referred to as an equiangular triangle because all the three angles are equal.

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 are the 4 different types of triangles?

This math worksheet gives your child practice identifying equilateral, isosceles, scalene, and right triangles.

What are the different triangles called?

There are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene.

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.

Do all triangles have 3 equal sides?

A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal.

What are the 5 types of triangles?

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

What are the three types of triangle?

What are the types of triangle?The sum of angles in any triangle is 180°. … An equilateral triangle has three equal sides and angles. … An isosceles triangle can be drawn in many different ways. … A right-angled triangle has one 90° angle. … A scalene triangle has three different angles and none of its sides are equal in length.More items…

What is a true triangle?

A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side.

What is the longest side of a right triangle called?

hypotenuseThe hypotenuse of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle. The other two sides are called the opposite and adjacent sides.

What do you call a polygon with 7 sides?

heptagonA five-sided shape is called a pentagon. A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides… The names of polygons are derived from the prefixes of ancient Greek numbers.

What 3 angles make a triangle?

In a Euclidean space, the sum of angles of a triangle equals the straight angle (180 degrees, π radians, two right angles, or a half-turn). A triangle has three angles, one at each vertex, bounded by a pair of adjacent sides.

What are the characteristics of a triangle?

Properties of a triangleA triangle has three sides, three angles, and three vertices.The sum of all internal angles of a triangle is always equal to 1800. This is called the angle sum property of a triangle.The sum of the length of any two sides of a triangle is greater than the length of the third side.More items…
