Square Root Spiral
The Ancient Greeks worked out the values of square roots by drawing a series of right triangles where one side of each successive triangle is 1 unit (e.g. 1 cm) long. Draw your own diagram and use a ruler to measure the square roots of 2, 3, 4, 5, and so on. Check these values with a calculator.
