Solving equations
Isosceles triangles

The dynamic figure below shows different isosceles triangles, all of them with a side of 1 meter.

Describe the area of the triangle as a function of the length of its base. Examine the function you constructed and answer the questions below. Check your answers using measurements on the dynamic figure.

What is the largest possible area of an isosceles triangle with 1-meter long sides? What is the length of the base of such a triangle?

  • What are your options in choosing the length of the base to construct an isosceles triangle with 1-meter long sides and an area that is half the maximum possible area?
