hello, dear!

anonymous · Answer

Aloha!! :DD

imstuck · Answer

It's B, all the sides have the length of 2 units.  Even though the diagonal ones look longer, they are not.  They are 2 units, too, even though they go through the squares on the grid at a slant instead of straight across on the lines.

Woops! :(
No, the diagonals are `not` of length 2.

If I form a right triangle like this,
performing the Pythagorean Theorem shows us that the diagonal length is $\Large\rm 2\sqrt2$

zepdrix · Answer

You can kind of tell by the picture as well,
the diagonal ones look longer, at least to me.

zepdrix · Answer

Woops I didn't go my @ correctly on his name :) lol

anonymous · Answer

IMStuck is a her* ..  oh, no worries.. so you didn't get b? :(

zepdrix · Answer

No, it should be option C.
:c

anonymous · Answer

@Cosmichaotic  -may you check this , please!?

anonymous · Answer

A regular polygon is defined as have equivalent lengths of sides in all respects. It looks like some are 2 and some are a little longer. This isn't a regular polygon.

anonymous · Answer

So it's between C or D

anonymous · Answer

Yeah, if they are longer, it can't be b!
Well the choices were down to "B" and "C"...
Now that you've confirmed I can eliminate "B", then it must be "C"..

anonymous · Answer

We can figure out if the longer lengths are 4 units long or 2sqrt(2) by using the Pythagorean Theorem as @zepdrix has shown in his triangle above.

anonymous · Answer

The chice cannot be A or B because this is not a regular polygon and A and B both state that it is right? So it's between C and D

anonymous · Answer

if you see that 2^2 + 2^2 = c^2 or 8 = c^2 then
Take the sqrt of both sides to get c = sqrt(8) or 2sqrt(2), C

anonymous · Answer

Ah, see - it is C! :D

anonymous · Answer

That's using a^2 + b^2 = c^2 - The Pathagorean Theorem that @zepdrix drew above by making a triangle by making the longer line the hypotenuse. I hope this is making sense... we need like Skype or something.. haha

anonymous · Answer

Yep, you got it.

anonymous · Answer

Ah, at last, the confirmation is clear ! :)

anonymous · Answer

Most important things to have learned here

1. Regular polygons have all equal line lengths making them.
2. Any line with a slope can be used to make a triangle of which the longest line is the hypotenuse.
   2a. By which we use the length of x and the length of y as our two lengths of the legs and the hypotenuse can then be figured by using the Pythagorean theorem.
