A pie can be cut into more than seven pieces by making four diameter cuts.

True or False?

I'm pretty sure it's true

True

a diameter cut goes through the middle of the pie

if we do one cut, we get 2 pices

if we do another one, perpendicular to first, we get 4 pieces

another cut (3rd), with a line that is an angle bisector of the other 2 lines, we get 6 pieces

4th, with a line perpendicular to the 3rd, we get 8 pices

8>7 so true
