What is a triangle in math definition?

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.

Which is best definition of a triangle?

The definition of a triangle is a shape with three angles and three sides. A right-angled, flat, triangular instrument used in drawing geometric figures.

What is a triangle BYJU's?

A triangle is a polygon with three sides having three vertices. 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. In other words, a triangle is defined as a three-sided two-dimensional figure whose interior angles are equal to 180°.

What is triangle class7?

What is a triangle in simple words?

A triangle is a shape, or a part of two dimensional space. It has three straight sides and three vertices. The three angles of a triangle always add up to 180° (180 degrees). It is the polygon with the least possible number of sides.


Which are triangles?

In Geometry, triangles are the type of polygons, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all the three angles of a triangle is equal to 180°.


What does triangle mean in physics?

the triangle is a mathematical symbol which denotes change in a quantity . it is called delta. so delta v= final velocity -initial velocity,delta t=time during the final velocity – time during the initial velocity was recorded. 4.3K views.


Why is it called a triangle?

A polygon is a closed plane figure with three or more straight sides. Polygons each have a special name based on the number of sides they have. For example, the polygon with three sides is called a triangle because “tri” is a prefix that means “three.” Its name also indicates that this polygon has three angles.


What is made of triangle?

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 triangle and its type?

Types of Triangles

Types of Triangle Based on Sides Types of Triangles Based on Angles
Equilateral Triangle Acute-Angled Triangle (Acute Triangle)
Isosceles Triangle Right-Angled Triangle (Right Triangle)
Scalene Triangle Obtuse-Angled Triangle (Obtuse Triangle)

Why do we study triangle?

They are one of the first shapes studied in geometry. Triangles are particularly important because arbitrary polygons (with 4, 5, 6, or n sides) can be decomposed into triangles. Thus, understanding the basic properties of triangles allows for deeper study of these larger polygons as well.


What is a triangle and its properties?

A triangle has three sides, three angles, and three vertices. The sum of all internal angles of a triangle is always equal to 180°. 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.


How do you introduce a triangle?

  • A triangle is a closed curve which is formed by 3 line segments.
  • Sides : AB, BC, CA.
  • Vertices: A, B, C.
  • Angles: ∠BAC, ∠ABC , ∠BCA.
  • Base: Its is the bottom side of the triangle.
  • Base angles: Two angles which touch the base.

  • What is hypotenuse math?

    1 : the side of a right-angled triangle that is opposite the right angle.


    What is triangle with diagram?

    A triangle diagram is defined by a set of curves (levels) in a regular triangle. The endpoints of each level lie on the boundary of the triangle except for the vertices. The levels are colored in 3 colors (red, blue and green) according to the triangle sides where the levels end.


    What does triangle mean in science?

    A triangle in a chemical reaction is the capital Greek symbol delta Δ . The symbol means heat in the chemical reaction.


    What does ∆ mean in chemistry?

    It means heat. So you could put something on a hot plate, crank up the temperature then you'd be carrying out the action indicated by Δ .


    What does ∆ mean in physics?

    What does ∆ mean in physics? In general physics, delta terms change and delta-v is simply a change in velocity. The Greek uppercase letter delta is the standard mathematical symbol to represent change in some quantity. Depending on the situation, delta-v can be either a spatial vector (Δv) or scalar (Δv).


    When a triangle is formed?

    All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.


    What is called angle?

    In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles.


    Who is the father of triangle?

    Many have speculated that the claims of the 5th-century BC Greek mathematician Pythagoras being the first to deduce facts about right-angled triangles just did not add up. Some believe later commentaries indicate it was the collaborative work of his followers, the Pythagoreans.
