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
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.
Equilateral triangle. All angles are 60º, and all side lengths are congruent to one another.
Add the length of all sides. A regular polygon is a polygon where all sides and angles are congruent, so a shortcut is to know the length of one side and multiply it by the number of sides.
If it is a regular polygon--meaning that all the sides are congruent and all the angles are congruent, then the formula for area of the polygon is A=1/2 ap Here a represents the apothem, which is the distance from the center of the polygon to the midpoint of one side. p represents the perimeter of the polygon found by multiplying one side length by the number of sides. If you only know one variable such as side length, you can find the perimeter and you can find the apothem using trigonomety.
