**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
