Hint: Polygons are two-dimensional geometric objects composed of points and straight lines connected together to close and form a single shape. Irregular polygons are polygons that have unequal angles and unequal sides, as opposed to regular polygons which are polygons that have equal sides and equal angles.
Complete step-by-step answer:
Scalene triangle
A scalene triangle is a triangle in which all the three sides are in different lengths, and all the three angles are of various measures.
So it is an irregular polygon.
Square
Square is a regular quadrilateral, which has all the four sides of equal length and all four angles are also equal.
So it is not an irregular polygon.
Equilateral triangle
An equilateral triangle is a triangle whose three sides all have the same length and all the angles are equal.
So it is not an irregular polygon.
Pentagon
A pentagon is a geometrical shape, which has five sides and five angles.
So it is an irregular polygon.
So, option (A) and (D) are the correct answer.
Note: Even though some of the polygons have some sides that are the same length, like the isosceles triangle and rectangle, they are still classified as irregular polygons because not all sides are the same length.
If the question does not specify how many answer choices to select, select all that apply.
The correct answer may be just one of the choices or as many as all of the choices, depending on the question.
No credit is given unless you select all of the correct choices and no others.
If the question specifies how many answer choices to select, select exactly that number of choices.
