In the figures shown, the side lengths of the squares are the same as the side lengths of their respective triangles.

Figure 1: g= 6cm h= 8cm i= 10cm; Figure 2: d= 7cm e= 9cm f=10cm; Figure 3: a= 3cm b=4cm c= 5cm

In Figure 1, is a right triangle. The area of square G + area of square H is equal to the area of square I.

In Figure 2, is an acute triangle. The area of square D + area of square E is not equal to the area of square F.

is an obtuse triangle.
B.
is an acute triangle.
C.
is an isosceles triangle.
D.
