Perimeter
To calculate the perimeter of an isosceles triangle, the expression 2s + b is used, where s represents the length of the two congruent sides and b represents the length of the base. Observe how the perimeter of the isosceles triangle changes as the value of s is increased.
What effect, if any, does increasing the value of s have on the expression?
