In an isosceles triangle, there are two sides that are congruent (meaning that they have the same length).
The other side is considered to be the base.
Let x be the length (in cm) of the congruent sides.
The perimeter is the sum of the lengths of all sides.
perimeter=4%2Bx%2Bx=4%2B2x
4%2B2x=24 --> 4%2B2x-4=24-4 --> 2x=20 --> 2x%2F2=20%2F2 --> highlight%28x=10%29
