equable isosceles triangles
the area value = perimeter value
for isosceles triangles (including an equilateral triangle, in Q2) with integer heights
this work involves: surds,
rationalising (simple) denominators
and pythagoras
three triangles sum to the large (isosceles) triangle
and 2a + 2c = ah since P = A
