Let me work through identifying each quadrilateral type based on the markings shown.
Step 1: Understanding the markings
- Tick marks (|) on sides indicate those sides are equal in length
- Double tick marks (||) also indicate equal lengths (different from single ticks)
- Right angle symbols (□) indicate 90-degree angles
Step 2: Analyzing each shape
Shape 1: Opposite sides have matching tick marks (both pairs of opposite sides are parallel and equal). No right angles. This is a
parallelogram.
Shape 2: All four sides have tick marks (all equal), and all four corners have right angle symbols. This is a
square.
Shape 3: Four sides with no special markings indicating equal sides or right angles. This is just a general
quadrilateral.
Shape 4: Opposite sides have double tick marks (opposite sides are parallel and equal). No right angles. This is a
parallelogram.
Shape 5: Four sides, no markings for equal sides or right angles. This is a general
quadrilateral.
Shape 6: Has one pair of parallel sides (indicated by the single tick mark pattern on top and bottom). This is a
trapezoid.
Shape 7: All four sides have tick marks (all equal), and all four corners have right angle symbols. This is a
square.
Shape 8: Opposite sides have matching tick marks (opposite sides are parallel and equal). No right angles. This is a
parallelogram.
Shape 9: Has one pair of parallel sides (top and bottom marked with tick marks). This is a
trapezoid.
Shape 10: All four sides have tick marks (all equal), and all four corners have right angle symbols. This is a
square.
Shape 11: Opposite sides have matching tick marks (opposite sides are parallel and equal). No right angles. This is a
parallelogram.
Shape 12: Has one pair of parallel sides (marked with tick marks). This is a
trapezoid.
Let me verify my answers:
- Parallelograms: 1, 4, 8, 11 (opposite sides parallel and equal, no right angles required)
- Squares: 2, 7, 10 (all sides equal AND all right angles)
- Trapezoids: 6, 9, 12 (one pair of parallel sides)
- General quadrilaterals: 3, 5 (no special properties indicated)
Final Answer:
1) Parallelogram
2) Square
3) Quadrilateral
4) Parallelogram
5) Quadrilateral
6) Trapezoid
7) Square
8) Parallelogram
9) Trapezoid
10) Square
11) Parallelogram
12) Trapezoid
