Construct this design using only compasses
Can you work out the fraction of the original triangle that is
covered by the inner triangle?
Construct a line parallel to one side of a triangle so that the
triangle is divided into two equal areas.
Change the squares in this diagram and spot the property that stays
the same for the triangles. Explain...
Explain how to construct a regular pentagon accurately using a
straight edge and compass.
Join in this ongoing research. Build squares on the sides of a
triangle, join the outer vertices forming hexagons, build further
rings of squares and quadrilaterals, investigate.
Christopher and Tim used different methods, one by solving equations, the other using vector and scalar products.
