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
