Use the interactivity to find all the different right-angled triangles you can make by just moving one corner of the starting triangle.
What is the total area of the four outside triangles which are
outlined in red in this arrangement of squares inside each other?
Can you help the children find the two triangles which have the

A tennis ball is served from directly above the baseline (assume
the ball travels in a straight line). What is the minimum height
that the ball can be hit at to ensure it lands in the service area?
Follow the instructions and you can take a rectangle, cut it into 4 pieces, discard two small triangles, put together the remaining two pieces and end up with a rectangle the same size. Try it!
In a right angled triangular field, three animals are tethered to posts at the midpoint of each side. Each rope is just long enough to allow the animal to reach two adjacent vertices. Only one animal. . . .
Can you make a right-angled triangle on this peg-board by joining
up three points round the edge?
If the sides of the triangle in the diagram are 3, 4 and 5, what is
