Attributes of Shapes — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Every square is also a:
A) Trapezoid
B) Triangle
C) Rectangle
D) Pentagon
A rectangle is any 4-sided shape with 4 right angles, and a square fits that rule — it just adds the extra requirement that all 4 sides are equal.
2. Which polygon has more vertices than a heptagon?
A) Hexagon
B) Pentagon
C) Octagon
D) Quadrilateral
A heptagon has 7 vertices, and an Octagon has 8 — exactly one more — making the octagon the next polygon in the family of shapes.
3. Which pair of lines forms a right angle where they meet?
A) Parallel lines
B) Curved lines
C) Perpendicular lines
D) Skew lines
Perpendicular lines are defined as two lines that cross to make a 90-degree corner — that 90-degree corner is exactly what a right angle is.
4. A quadrilateral with 2 pairs of parallel sides but no right angles could be a:
A) Rectangle
B) Square
C) Parallelogram
D) Trapezoid
A parallelogram only requires 2 pairs of parallel sides — its angles can lean, so it does not need right angles like a rectangle would.
Part B: Fill in the Blank
Write the correct answer on each line.
1. A trapezoid has exactly 1 pair of parallel sides.
A trapezoid has exactly 1 pair of parallel sides — the other two sides slant toward each other, which is what makes the shape look like a tilted bucket.
2. A polygon where not all sides are equal is called an irregular polygon.
When a polygon's sides are mismatched in length, it breaks the even pattern of a regular shape — that is why we call it irregular.
3. A hexagon has 3 more vertices than a triangle.
A hexagon has 6 vertices and a triangle has 3, so subtracting 6 minus 3 gives 3 extra vertices in the hexagon.
4. All squares are rhombuses because they have 4 equal sides.
The rule for being a rhombus is having 4 sides of equal length, and a square meets that rule perfectly — its 4 right angles just make it a special kind of rhombus.
5. Parallel sides in a shape go in the same direction and never meet.
Parallel sides keep the same distance between them no matter how far they are extended, which means they never touch or meet at any point.
