A pentagon has 5 sides and its 5 interior angles add up to 540 degrees
A square is a four-sided shape with all sides equal and all angles equal.
hexagon
Absolutely !
*the. Answer is the Square.
Yes! Interestingly enough, the sum of the angles of any four-sided shape equals 360, the same number of degrees in a circle. The sum of the angles of any triangle equals 180, and 180 times two equals 360.
a congruent shape HAS TO HAVE ALL CONGRUENT ANGLES OR IT WOULDNT BE A CONGRUENT sHAPE
Dodecagon is the name for the regular 12 sided polygon, meaning that all its side lengths and angles are the same. Not sure if there is a name for a general 12 sided 2d shape.
n: same as the number of sides.
There is no four-sided shape (quadrilateral) with four equal sides where no angles are the same. The diagonally-opposing angles must be the same, and opposing sides must be parallel. The only quadrilateral that fits that description is a parallelogram.

A six sided shape is called a hexagon.If all the sides have the same length and all the internal angles are the same it is a Regular hexagon.
The same number, 12.
