Question

If you’re good at geometry could somebody help me with this?

Answer 1

Answer:

The pentagon

Step-by-step explanation:

It is the only shape out of the four that is not a quadrilateral. While every other choice has four sides, the pentagon has five.

An argument could also be made for the gray square. It is the only one that is not colored white on the inside.

Answer 2

The pentagon does not belong because it has 5 sides while the other 3 shapes have only 4 sides.
