Three triangles and a square
In this presentation and collection of student worksheets a diagram shows a square and three right angled triangles, with each shape sharing a common side. Some of the lengths are given in surd form, from which students have to find the area of the square.
The solution involves the use of Pythagoras’ theorem and surds. Each of the fourteen student worksheets have different dimensions, but the solutions all have something in common.
