Quadrilaterals Worksheets - Math Monks - Free Printable

Let's solve the problem step by step by identifying each quadrilateral based on its properties (sides, angles, and markings).

Key Properties of Quadrilaterals:

- Rectangle: 4 right angles, opposite sides equal and parallel.
- Square: 4 right angles, all sides equal, opposite sides parallel.
- Rhombus: All sides equal, opposite sides parallel, opposite angles equal.
- Parallelogram: Opposite sides equal and parallel, opposite angles equal.
- Trapezoid: One pair of opposite sides parallel.
- Kite: Two pairs of adjacent sides equal, one diagonal is a line of symmetry.
- Irregular Quadrilateral: No special properties.

Now let’s analyze each figure:

---

1.

- Has four right angles (marked with squares).
- Opposite sides are marked as equal (double tick marks).
- Opposite sides are parallel (implied by tick marks and shape).
- Not all sides equal — only opposite sides equal.

✔ This is a Rectangle.

---

2.

- Has four right angles (squares in corners).
- All four sides have same tick marks, meaning all sides are equal.
- So it has 4 right angles + all sides equal.

✔ This is a Square.

---

3.

- Only one pair of opposite sides appears parallel (based on shape).
- It has no right angles shown.
- No sides are marked as equal.
- Looks like a trapezoid.

✔ This is a Trapezoid.

---

4.

- Opposite sides are marked as equal (tick marks).
- Opposite sides are parallel (implied by shape and arrows).
- But no right angles.
- Not all sides equal.

✔ This is a Parallelogram.

---

5.

- Has one pair of opposite sides parallel (indicated by arrows).
- The other two sides are not parallel.
- No right angles or equal sides marked.

✔ This is a Trapezoid.

---

6.

- Has four right angles (squares in corners).
- All sides are marked with same tick marks, so all sides are equal.

✔ This is a Square.

> Wait — this looks identical to #2. But maybe just different orientation? Yes, same properties.

✔ Still a Square.

---

7.

- Has four right angles (squares in corners).
- All sides are marked as equal (tick marks on all sides).
- So again: 4 right angles + all sides equal.

✔ This is a Square.

> Note: #2, #6, and #7 all appear to be squares. Possibly intentional repetition for practice.

---

8.

- Two pairs of adjacent sides equal (each side has a tick mark).
- The shape is symmetric along one diagonal.
- No right angles.
- This matches the definition of a kite.

✔ This is a Kite.

✔ Final Answers:

1. Rectangle
2. Square
3. Trapezoid
4. Parallelogram
5. Trapezoid
6. Square
7. Square
8. Kite
