Two crescents and a triangle
This resource contains a diagram made from a circle, four semi-circular arcs and a rectangle with dimensions given in surd form. The challenge is to find the total area of a given shaded area.
The student worksheets each contain different dimensions for the diagram, but the solutions all have something in common.
The solution involves using the area of a circle and Pythagoras’ theorem. As an extension, students can be shown that Pythagoras’ theorem can be used with other similar shapes other than squares.
