It is an irregular polygon.
Same-side interior angles are supplementary. They are not always congruent, but in a regular polygon adjacent angles are congruent.
That would be called a regular polygon, one with congruent(equal) side legnths and congruent angles.
an 8 sided polygon that has congruent angles, but not congruent side lengths
A polygon has sides A polygon can have any number of side A polygon can not be curved so a circle is not a polygon Regular Polygon Has congruent sides and angles Has lines of symmetry Irregular Polygon Doesn't have any equal sides or angles Doesn't have any lines of symmetry

True. A convex polygon with more than four sides that has congruent interior angles must also have congruent sides, making it a regular polygon. Regular polygons are defined by having both equal angles and equal side lengths. Therefore, if a convex polygon has congruent interior angles, it is necessarily regular.
The description given would fit to that of an equilateral triangle.
It is a regular polygon
No, the definition of congruent polygons is that all corresponding SIDES are of equal length. All corresponding angles as well.
A rhombus, (or a square if the angles are measured in radians!), An irregular polygon with more than 4 sides, where 4 of the sides are congruent and the rest are all different lengths.
To show that the angles of a triangle are congruent without measuring them, you can use the properties of triangle congruence. If you can establish that the triangles are congruent through methods such as Side-Angle-Side (SAS) or Angle-Side-Angle (ASA), it follows that corresponding angles are congruent. Alternatively, you can use the fact that the sum of the angles in any triangle is always 180 degrees, which can demonstrate relationships between the angles without direct measurement.
Equilateral triangle. All angles are 60º, and all side lengths are congruent to one another.
