Regular
congurent angles are angles that have equal angles. Example, if you want to have equal angles, you have to have a shape that has equal sides
An equilateral triangle.
a polygon that has all angles congruent is an equiangular .....
It is simply a polygon with all equal angles. It is not a regular polygon - if that is what you are looking for.
A polygon with all sides and angles the same is called a "regular polygon."
A polygon with all interior angles congruent Is known as a regular polygon.
A polygon that all sides and angles are the same measurement is a regular polygon.
If all of its interior angles are equal then it is a regular polygon
They are if the triangle happens to be an equilateral one and they're all 60 degrees. Otherwise, no.
If you multiply 360 by the number of angles in the polygon and then subtract the sum of all the interior angles you will end up with the sum of all the exterior angles of the polygon.
If a polygon's lengths and angles are all equal it isn't an irregular polygon it's a regular polygon! :)
