1. Use the Circle with Centre through Point to draw 2 circles that are the same size. In other words each circle passes through the centre point of the other.[br]2. Use the Intersect tool to mark the top intersection of the 2 circles.[br]3. Now, using the line tool, draw lines joining this point of intersection with the centres of the circles and join the centres to each other to create a triangle.[br]4. Use the Distance of Length tool to measure the length of each side of this triangle.
