Below are sample questions representative of the exercises included on this worksheet and related 5.149 Distinguish Regular and Irregular Polygons skill assessments:

Problem 1Difficulty: Mastery
Which row gives the correct test for classifying any polygon as regular?
ACheck that it is a polygon, then check that every side and every angle matches
BCheck only that the figure has a name
CCheck only that the figure is drawn upright
DCheck that it has at least one equal side pair
Solution & Explanation:To classify a regular polygon, first make sure the figure is a polygon. Then verify that all side lengths and all angle measures are equal.
Problem 2Difficulty: Mastery
Two eight-sided polygons are compared. Polygon A has every side and angle matching. Polygon B has every side matching, but one angle is different. Which comparison is accurate?
AA is regular, and B is irregular
BA is irregular, and B is regular
CBoth A and B are regular
DNeither A nor B is a polygon
Solution & Explanation:Polygon A meets both regular conditions. Polygon B has unequal angles, so it is irregular.
Problem 3Difficulty: Mastery
Which statement is always true of an irregular polygon?
AIt is a polygon that is not both equal-sided and equal-angled
BIt always has a curved side
CIt is always open
DIt always has exactly five sides
