If the two equal sides of an isosceles triangle have length a, find the length of the third side that maximizes the area of the triangle.

To determine

To find: Length of the third side of the isosceles triangle so that it maximizes the area.

Explanation

Given: The two equal sides of an isosceles triangle have length a.

Solution:

Let the height of the isosceles triangle be h and base be b .

In Figure 1, AB is perpendicular on the base.

So, ABC be the right angle triangle.

Length of the BC be b2 .

In triangle ABC ,

sinθ=b2ab=2×a×sinθ

cosθ=hah=acosθ

Obtain the area of the triangle.

Z=12×b×h=12(2asinθ)(acosθ)=a2sinθcosθ=a22sin2θ

Differentiate Z with respect to θ .

dZdθ=a22×2cos2θ=a2cos2θ

For critical points, dZdθ=0

cos2θ =0
