Equilateral Triangle, Isosceles Triangle & Scalene Triangle | Maths

Equilateral triangle – When all the three sides of triangle are of equal length, we call it an Equilateral triangle.

Isosceles triangle – When two sides are of triangle are of equal length and one side is different in length from the other, we call it Isosceles triangle.

Scalene triangle – When all the sides of triangle are different in length, we call it Scalene triangle.




QUESTION 1

If the sides of triangle are 5 cm , 6 cm , 7 cm , then the triangle is ?

EXPLANATION

Equilateral triangle – When all the three sides of triangle are of equal length, we call it an Equilateral triangle.

Isosceles triangle – When two sides are of triangle are of equal length and one side is different in length from the other, we call it Isosceles triangle.

Scalene triangle – When all the sides of triangle are different in length, we call it Scalene triangle.

Here, sides of triangle are 5 cm , 6 cm , 7 cm

Since, all the sides of triangle are different in length, so the triangle formed by given side is Scalene Triangle

 

QUESTION 2

If the sides of triangle are 6 cm , 6 cm , 6 cm , then the triangle is ?

EXPLANATION

Equilateral triangle – When all the three sides of triangle are of equal length, we call it an Equilateral triangle.

Isosceles triangle – When two sides are of triangle are of equal length and one side is different in length from the other, we call it Isosceles triangle.

Scalene triangle – When all the sides of triangle are different in length, we call it Scalene triangle.

Here, sides of triangle are 6 cm , 6 cm , 6 cm

Since, all the three sides of triangle are of equal length, so the triangle formed by given side is An Equilateral Triangle




QUESTION 3

If the sides of triangle are 5 cm , 5 cm , 10 cm , then the triangle is ?

EXPLANATION

Equilateral triangle – When all the three sides of triangle are of equal length, we call it an Equilateral triangle.

Isosceles triangle – When two sides are of triangle are of equal length and one side is different in length from the other, we call it Isosceles triangle.

Scalene triangle – When all the sides of triangle are different in length, we call it Scalene triangle.

Here, sides of triangle are 5 cm , 5 cm , 10 cm

Since, two sides of triangle are of equal length and one is different, so the triangle formed by given side is An Isosceles Triangle
