Daily Lego Maths: Day 31

These three squares have the special property that the area of the two smaller squares together is equal to the area of the larger square.

Three squares made from 2 by 2 Lego bricks, arranged so that one edge of each square forms a side of a right-angled triangle. There is a yellow 4 by 4 square and a blue 3 by 3 square. The third square is a 5 by 5 square made up of a 3 by 3 blue square in the top left, with 16 yellow bricks arranged to the right and below to fill in the rest of the square

Can you find some more sets of three squares with this property?
What happens if you arrange them in a triangle?
