Problem-solving with equilateral triangles
At the Grecian Pizza Parlour, apprentice Ambrose receives an order for 50 equilateral triangle shaped pizzas with equilateral triangle shaped toppings. Ambrose uses the circular base and cuts to form the equilateral triangle base explaining about the properties of the shape. He makes tessellating toppings to cover the pizza. Three differentiated questions then reinforce understanding of angles in a triangle, use of a protractor and introduce an investigation about fitting different triangles into a 30cm square pizza box.
