What is a triangle and explain 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 is called triangle?

A triangle is a 3-sided polygon sometimes (but not very commonly) called the trigon. 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.

What is triangle Class 8?

Triangle Definition in Maths A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees. It means that the sum of the interior angles of a triangle is equal to 180°. It is a polygon having the least number of sides.

What are the 6 different 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.
• An equilateral triangle is a triangle with three congruent sides and three congruent angles.

What is a triangle class 7?

Triangle: A triangle is a simple closed curve made of three line segments. It has three vertices, three sides and three angles. Here in ΔABC, it has. Sides: \bar { AB }, \bar { BC }, \bar { CA }. Vertices: A, B, C.

What are the different types of angles of a triangle?

The different types of triangles are grouped by either their angles, lines or both. For example and equilateral triangle is a triangle whose SIDES are equal. A right triangle has one angle that is 90 degrees, also known as a right angle.

What are the basic triangles?

A triangle is a basic geometrical shape, with consists of three corners or vertices and three sides which are called line segments. There are various types of triangles some of them are :- Equilateral triangle, isosceles triangle, Scalene triangle, Right triangle, Special right triangle etc.

What are the names of the angles in a triangle?

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.

What are all the different triangles?

However, when combined, there are seven types of triangles: acute equilateral, right isosceles triangle, right scalene triangle, obtuse isosceles triangle, obtuse scalene triangle, acute isosceles triangle, and acute scalene triangle. We hope this helps!
