put the area = perimeter and solve the resulting equation:
work out the missing lengths using the tangents to circle property
add up to the area of the trapezium

equable trapeziums
beginning to appreciate that all tangential polygons with an incircle radius = 2 are equable
put the area = perimeter and solve the resulting equation:
ignore the heights from the previous task
work out the missing lengths using the tangents to circle property
the expressions need to be simplified
the areas of the four triangles
add up to the area of the trapezium
put the area = perimeter and solve the resulting equation:
work out the missing lengths using the tangents to circle property
