9. a) Calculate the areas of the three squares.
shorter leg is 2cm- area of square is 4cm2
longer leg is 3cm- area of square is 9cm2
hypotenuse is 4cm- area of square is 16cm2
b) Is this triangle a right triangle? Explain.
Yes the triangle is a right triangle because when you look at it there's a right angle. That means that where the two legs meet it's a 90 degree angle.
That is my answer I hope you understand what I was getting at.
