Answer 1

If a polygon has 4 sides, is it always a square?

Answer 2

No :3

Answer 3

pentagon has five sides.

Answer 4

so the first one is false

if it's a square, then it has 4 sides
but the opposite isn't true (eg: a rectangle has 4 sides but doesn't have to be a square)

Answer 5

Ohh okay! that makes sense!

Answer 6

similarly, the third one is false as well

if you have a rectangle, then you have 4 sides
but if you have 4 sides, then you don't always have a rectangle (you could have a square, some non-rectangular parallelogram, or some quadrilateral with no parallel sides)

Answer 7

and as @sshayer is saying, if you have 5 sides, then you have a pentagon. Or if you have a pentagon, then you have 5 sides. This is by definition of what "pentagon" means. So the second statement is true.

Answer 8

Thank you so much!!!
