Question

The perimeter of an isosceles triangle is 20 cm. If one of the two equal sides is 6 cm, then the third side is …..​

Answer 1

a triangle in which two sides are equal in length is called an isosceless triangle.

from question, we can see that length of two equal sides = 6 CM each

perimeter =20

6+6+x = 20

x = 8 cm

Answer 2

Answer:

8 cm

Explanation:

sum of two sides which is 6 cm is 12 cm

when we subtract the perimeter from 12 cm which is of two sides.(12-20)

Hence,we got 8 cm
