| The perimeter is the sum of the lengths of all sides of a geometric shape.
An isosceles triangle is a triangle in which the sides are equal in size.
1. Knowing the perimeter and length of the base, we calculate the sum of the two lateral sides:
36 – 10 = 26 cm.
2. Since the sides are equal, we calculate the length of each of them, dividing their sum by two:
26: 2 = 13 cm.
Answer: The length of the side in a triangle is 13 centimeters.
