  • Isosceles triangle

Triangles having two equal sides.

  • Pythagorean Theorem

If three lengths of a right triangle are a, b, and c, and the hypotenuse is c, a^2+b^2=c^2.

Solution

Let's draw a bisector of an angle. By triangle congruence, two triangles are congruent. (Attachment 1)

One isosceles triangle is two right triangles. (Attachment 2)

Applying Pythagorean Theorem,

Base: 12 cm

Height: 8 cm

Area of one triangle

=\dfrac{1}{2} \times 12\times 8

=48 cm²

Area of the rectangle

=16\times 12

=192 cm²

The figure is a sum of the areas of two triangles and one rectangle.

Area of the polygon

=2\times 48+192

=96+192

=288 cm²
