Attributes of Shapes — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Which statement about a rhombus is always true?
A) It has 4 right angles
B) It has 4 equal sides
C) It has no parallel sides
D) It has only 2 equal sides
A rhombus has 4 equal sides like a square, but its angles are not always right angles, which is the key difference.
2. Which shape has the most lines of symmetry?
A) Rectangle
B) Square
C) Trapezoid
D) Parallelogram
A square is a special rectangle because it has 4 right angles and the added property that all sides are equal.
3. A polygon with 6 equal sides and 6 equal angles is called a:
A) Regular pentagon
B) Regular hexagon
C) Regular octagon
D) Regular heptagon
A regular hexagon has 6 lines of symmetry, matching its 6 equal sides.
4. Which of these is NOT a quadrilateral?
A) Square
B) Trapezoid
C) Pentagon
D) Parallelogram
A pentagon has 5 sides. The prefix 'penta' means five.
Part B: Fill in the Blank
Write the correct answer on each line.
1. A parallelogram has 2 pairs of parallel sides.
A parallelogram has 2 pairs of parallel sides; opposite sides are parallel to each other.
2. An equilateral triangle has 3 equal sides and 3 equal angles.
An equilateral triangle has 3 equal sides and 3 equal angles, each measuring 60 degrees.
3. A circle has infinite lines of symmetry.
A circle has infinite lines of symmetry because any line through its center divides it into two equal halves.
4. Every square is a rhombus, but not every rhombus is a square.
A square has 4 equal sides (like a rhombus) and 4 right angles. A rhombus only requires 4 equal sides.
5. A right angle can be found at the corner of a rectangle.
Rectangles have right angles at every corner, making them a common example of where right angles appear.
