Explanation:
We are asked to identify each quadrilateral. A quadrilateral is any shape with four sides and four corners (vertices). The most common types include:

- Rectangle: 4 right angles, opposite sides equal and parallel.
- Square: All sides equal, all angles 90° — a special rectangle.
- Parallelogram: Opposite sides parallel and equal; angles not necessarily 90°.
- Rhombus: All sides equal; opposite sides parallel; angles not necessarily 90° — a special parallelogram.
- Trapezoid (or trapezium): At least one pair of parallel sides (in US definition: exactly one pair).
- Kite: Two pairs of adjacent sides equal; one pair of opposite angles equal.

Now let’s go through each numbered shape (1–12) and name it based on its appearance:

1. Orange shape: 4 sides, all angles look 90°, opposite sides equal → Rectangle
2. Purple shape: 4 sides, one pair of parallel sides (top and bottom), non-parallel sides slant inward → Trapezoid
3. Peach shape: 4 sides, both pairs of opposite sides parallel, angles not 90° → Parallelogram
4. Pink shape: 4 sides, two pairs of adjacent sides equal, looks like a diamond with symmetry across vertical axis → Kite
5. Light blue shape: 4 equal sides, all angles 90° → Square
6. Green shape: 4 sides, both pairs of opposite sides parallel, angles not 90° → Parallelogram
7. Teal shape: 4 sides, one pair of parallel sides (top & bottom), slanted sides → Trapezoid
8. Lavender shape: 4 sides, two pairs of adjacent sides equal, but not symmetric like a kite? Wait — actually, this looks like a kite, but rotated. Let’s double-check: top two sides equal, bottom two sides equal, one diagonal is axis of symmetry → yes, Kite
9. Pink rectangle: 4 right angles, opposite sides equal → Rectangle
10. Dark green shape: 4 sides, only one pair of parallel sides (top & bottom), slanted sides → Trapezoid
11. Tan shape: 4 equal sides, angles not 90°, both pairs of opposite sides parallel → Rhombus
12. Blue shape: 4 sides, only one pair of parallel sides (left & right? No — actually top and bottom are not parallel; left and right look slanted similarly — wait, better check: it has one pair of parallel sides — the top and bottom appear parallel, sides slant inward → Trapezoid

Let me re-verify tricky ones:

- #8: Looks like a dart-shaped kite (concave kite)? But in standard elementary worksheets, if it has two distinct pairs of adjacent equal sides and one axis of symmetry, it's still called a kite — even if concave (though some definitions require convex). Given context, likely Kite.
- #11: All sides same length, angles not right angles, opposite sides parallel → definitely Rhombus.
- #12: Top and bottom are horizontal and parallel; left and right are slanted but not parallel → Trapezoid.
