# Composite Figures

Overlap, inscribe, and circumscribe a collection of simple geometric shapes to make a complex, composite figure.

All of the triangles in the diagram are equilateral and share a center with all the circles. All of the internal circles and triangles are inscribed in the appropriate triangles and circles, respectively.

If the green area is equal to the red area, is the purple area equal to the yellow area?

What is the area of the region enclosed by the graph of \(x^2+y^2=|x|+|y|\)?

\[\] **Notation**: \( | \cdot | \) denotes the absolute value function.

7 non-overlapping unit circles are inscribed inside a large circle as shown below. What is the area of the shaded region?
