NNAT Geometric Concepts and Shape Properties 2 — Questions and Answers
Question 1: Which term describes two shapes that are exactly the same size and shape?
- Similar
- Parallel
- Congruent (Correct answer)
- Symmetric
Correct answer: Congruent
Congruent shapes are identical in size and shape, even if they have been rotated or flipped.
Question 2: A shape with exactly 5 sides is called a:
- Hexagon
- Pentagon (Correct answer)
- Octagon
- Quadrilateral
Correct answer: Pentagon
A pentagon has 5 sides; the prefix 'penta-' means five in Greek.
Question 3: What do you call two lines in the same plane that never intersect, no matter how far they extend?
- Perpendicular
- Intersecting
- Parallel (Correct answer)
- Diagonal
Correct answer: Parallel
Parallel lines maintain the same distance apart and never meet, unlike intersecting or perpendicular lines.
Question 4: Which of the following is NOT a quadrilateral?
- Square
- Rectangle
- Triangle (Correct answer)
- Trapezoid
Correct answer: Triangle
A triangle has only 3 sides, while a quadrilateral must have exactly 4 sides.
Question 5: A regular shape has 8 equal sides. What is it called?
- Heptagon
- Hexagon
- Octagon (Correct answer)
- Nonagon
Correct answer: Octagon
An octagon has 8 sides; the prefix 'octa-' means eight, as in 'octopus' with its eight arms.
Question 6: Which property do a square AND a rhombus BOTH share?
- Four right angles
- Four equal sides (Correct answer)
- No parallel sides
- Only two equal sides
Correct answer: Four equal sides
Both a square and a rhombus have four sides of equal length, though only the square also has four right angles.
Question 7: How many vertices (corners) does a pentagon have?
- 4
- 5 (Correct answer)
- 6
- 7
Correct answer: 5
A pentagon has 5 sides and therefore 5 vertices, since the number of vertices equals the number of sides in any polygon.
