Generate three random numbers to determine the side lengths of a triangle. What triangles can you draw?
A game in which players take it in turns to turn up two cards. If they can draw a triangle which satisfies both properties they win the pair of cards. And a few challenging questions to follow...
A game in which players take it in turns to try to draw quadrilaterals (or triangles) with particular properties. Is it possible to fill the game grid?
Using LOGO, can you construct elegant procedures that will draw this family of 'floor coverings'?
Triangle ABC is equilateral. D, the midpoint of BC, is the centre of the semi-circle whose radius is R which touches AB and AC, as well as a smaller circle with radius r which also touches AB and AC. What is the value of r/R?
Is it possible to find the angles in this rather special isosceles triangle?
You are only given the three midpoints of the sides of a triangle. How can you construct the original triangle?
