A right scalene triangle.
A 16 sided polygon.
A regular polygon has equal lengths of each side, AND the same angle between each of the sides. A Square is a polygon, an equilateral triangle is a polygon, a pentagon is a five - sided polygon, and so on.
An irregular septagon: the right-angle will prevent it being regular.
A right triangle.
The interior angle of a heptagon (a 7-sided regular polygon), rounded to two decimal places, is equal to 180 - ((180 / 7) x 2) = 128.57 degrees.

A 16 sided polygon.
polygon
A regular polygon has equal lengths of each side, AND the same angle between each of the sides. A Square is a polygon, an equilateral triangle is a polygon, a pentagon is a five - sided polygon, and so on.
A rhombus, an equal sided parallelogram or an equal sided quadrilateral with no right angles.
So, the Sum of the interior angles for a 21 – sided polygon is equal to 3420°.
An irregular septagon: the right-angle will prevent it being regular.
A right triangle.
interior angle of an n-sided polygon = (180(n-2)/n)°interior angle of a 24-sided polygon = (180x22/24)° = 165°
The interior angle of a heptagon (a 7-sided regular polygon), rounded to two decimal places, is equal to 180 - ((180 / 7) x 2) = 128.57 degrees.
Each interior angle in 12-sided polygon is 150 degrees.
The angles of a 8 sided Polygon is 45 degrees.
