IT MEANS THAT IS A REGULAR POLYGON
THAT IS EQUANGULAR AND EQUELATELAL.
What does it mean to name a triangle by its sides and by its angles?
I know isosolese, acute, right, etc. are examples of angles, what are examples of names by the sides?

so if I use Isosolese and acute that would be naming by the angle (acute) and Isosolese (sides)
by angles, a triangle could be
acute: all angles less than 90
right-angled: one angle 90º, the other two acute
obtuse: one of the angles is greater than 90º
by sides, a triangle could be
scalene: all sides are of different lengths
isosceles: two of the sides are equal
equilateral: all 3 sides are equal
of course an isosceles triangle also has two angles equal, and an equilateral triangle has 3 60º angles.
