Below are sample questions representative of the exercises included on this worksheet and related 4.155 Classify Two Dimensional Figures by Lines and Angles skill assessments:

Problem 1Difficulty: Mastery
Look at Figure ZZ, a diamond-shaped rhombus with a diagonal drawn inside. Which statement about the outside figure is true?
AThe outside figure has two pairs of parallel sides and no right angles.
BThe diagonal makes the outside figure have four right angles.
CThe outside figure has no pairs of parallel sides.
DThe outside figure is a right triangle.
Solution & Explanation:The diagonal is inside the rhombus and is not an outside side. The outside rhombus has opposite sides parallel and no right angles.
Problem 2Difficulty: Mastery
A student compares a rectangle and a slanted parallelogram. Which property do they share, and which property differs?
AThey both have two pairs of parallel sides; only the rectangle has right angles.
BThey both have no pairs of parallel sides; only the parallelogram has right angles.
CThey both have four right angles; only the rectangle has parallel sides.
DThey both have exactly one pair of parallel sides; neither has angles.
Solution & Explanation:Rectangles and parallelograms both have two pairs of parallel sides. A rectangle has right angles, while a slanted parallelogram does not.
Problem 3Difficulty: Mastery
Three clues describe a figure: it is not a triangle, it has exactly one pair of parallel sides, and it has no right angles. Which statement is the best classification?
AIt has parallel sides but no perpendicular sides.
BIt has no parallel sides and one right angle.
CIt has two pairs of parallel sides and four right angles.
DIt has perpendicular sides but no parallel sides.
Solution & Explanation:The clues say the figure has a pair of parallel sides. Because it has no right angles, it has no perpendicular sides.
