As we discussed in the introduction, a triangle is a type of polygon, which has three sides, and the two sides are joined end to end is called the vertex of the triangle. An angle is formed between two sides.This is one of the important parts of geometry. Some major concepts, such as Pythagoras theoremand trigonometry, are dependent on triangle pro...
There are three angles in a triangle. These angles are formed by two sides of the triangle, which meets at a common point, known as the vertex. The sum of all three interior angles is equal to 180 degrees. If we extend the side length outwards, then it forms an exterior angle. The sum of consecutive interior and exterior angles of a triangle is sup...
Each and every shape in Maths has some properties which distinguish them from each other. Let us discuss here some of the properties of triangles. 1. A triangle has three sides and three angles. 2. The sum of the angles of a triangle is always 180 degrees. 3. The exterior angles of a triangle always add up to 360 degrees. 4. The sum of consecutive ...
On the basis of length of the sides, triangles are classified into three categories: 1. Scalene Triangle 2. Isosceles Triangle 3. Equilateral Triangle On the basis of measurement of the angles, triangles are classified into three categories: 1. Acute Angle Triangle 2. Right Angle Triangle 3. Obtuse Angle Triangle
A perimeter of a triangle is defined as the total length of the outer boundary of the triangle. Or we can say, the perimeter of the triangle is equal to the sum of all its three sides. The unit of the perimeter is same as the unit of sides of the triangle. If ABC is a triangle, where AB, BC and AC are the lengths of its sides, then the perimeter of...
The area of a triangleis the region occupied by the triangle in 2d space. The area for different triangles varies from each other depending on their dimensions. We can calculate the area if we know the base length and the height of a triangle. It is measured in square units. Suppose a triangle with base ‘B’ and height ‘H’ is given to us, then, the ...
In case, if the height of a triangle is not given, we cannot be able to use the above formula to find the area of a triangle. Therefore, Heron’s formula is used to calculate the area of a triangle, if all the sides lengths are known. First, we need to calculate the semi perimeter (s). s = (a+b+c)/2, (where a,b,c are the three sides of a triangle) N...
Question 1: If ABC is a triangle where AB = 3cm, BC=5cm and AC = 4cm, then find its perimeter. Solution: Given, ABC is a triangle. AB = 3cm BC = 5cm AC = 4cm As we know by the formula, Perimeter = Sum of all three sides P = AB + BC + AC P = 3+5+4 P = 12cm

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.
A simple closed curve or a polygon formed by three line-segments (sides) is called a triangle. The above shown shapes are triangles. The symbol of a triangle is ∆. A triangle is a polygon with three sides. In the given figure ABC is a triangle. AB, BC and CA are its sides.
Sep 19, 2024 · Triangles are polygons with three sides. The word “Tri” means three and therefore a figure with 3 angles is a triangle. It is formed with the help of three-line segments intersecting each other, a triangle has 3 vertices, 3 edges, and 3 angles. It is a 2-dimensional polygon in Euclidean geometry.
