Step-by-step solution for: Properties of Quadrilaterals Worksheets - Math Monks
Absolutely! Since I can’t view or process images, I’ll solve this Properties of Quadrilateral Worksheet based on standard geometry knowledge. This is a common chart used to compare properties of six key quadrilaterals: Parallelogram, Rectangle, Square, Trapezoid, Isosceles Trapezoid, and Kite.
I’ll fill in the table with ✔ for “yes” (property applies) and ✘ for “no” (property does not apply), along with brief explanations for each.

## 📘 Explanations by Quadrilateral Type
---
- Definition: A quadrilateral with two pairs of parallel sides.
- Properties:
- Opposite sides are parallel and congruent → ✔
- Opposite angles are congruent → ✔
- Diagonals bisect each other → ✔
- Diagonals are not necessarily congruent → ✘
- Sides are not all congruent unless it’s a rhombus → ✘
- Angles are not necessarily right angles → ✘
---
- Definition: A parallelogram with four right angles.
- Properties:
- Inherits all parallelogram properties → ✔ for opposite sides parallel/congruent, opposite angles congruent, diagonals bisect each other
- Diagonals are congruent → ✔
- Four right angles → ✔
- Sides are not necessarily all equal → ✘
---
- Definition: A rectangle that is also a rhombus (all sides equal).
- Properties:
- All properties of parallelogram, rectangle, and rhombus → ✔ for everything except trapezoid/kite-specifics
- Four congruent sides → ✔
- Four right angles → ✔
- Diagonals are congruent and bisect each other → ✔
---
- Definition: A quadrilateral with exactly one pair of parallel sides (some definitions allow "at least one" — we use strict definition here).
- Properties:
- Only one pair of opposite sides parallel → so “opposite sides parallel” = ✘
- No guarantee of congruent sides or angles → ✘ for most
- Diagonals do not necessarily bisect each other or be congruent → ✘
- Not a parallelogram → doesn’t inherit those properties
---
- Definition: A trapezoid with non-parallel sides congruent and base angles congruent.
- Properties:
- One pair of parallel sides → still doesn’t satisfy “opposite sides parallel” → ✘
- Diagonals are congruent → ✔ (key property!)
- Does not have diagonals that bisect each other → ✘
- Not all sides congruent → ✘
- Not all angles right → ✘
---
- Definition: A quadrilateral with two distinct pairs of adjacent congruent sides.
- Properties:
- No opposite sides are necessarily parallel → ✘
- Diagonals are perpendicular, and one diagonal bisects the other → but not both bisect each other → ✘
- One pair of opposite angles are congruent (not both) → so “opposite angles congruent” = ✘
- Four sides congruent? Only if it’s a rhombus → but typically, kites have two pairs of adjacent sides equal → ✔ only if specified as rhombus, but generally, yes for “four sides congruent” only if it's a square/rhombus — wait, correction:
> ❗️Important Clarification:
A kite has two pairs of adjacent congruent sides, not necessarily all four sides equal. So “Four sides congruent” is only true if it’s a rhombus. But since a rhombus is a special kite, technically some kites have 4 congruent sides — however, in basic classification, “Four sides congruent” is marked ✔ for Kite because a rhombus *is* a type of kite.
✔ So yes — a kite can have four congruent sides (if it’s a rhombus), so we mark it ✔.
But note: In many curricula, they distinguish between “kite” and “rhombus”, so sometimes “four sides congruent” is left ✘ for kite. To avoid confusion:
> 💡 Best Practice: If the worksheet expects “kite” to mean a non-rhombus kite, then mark ✘. But strictly speaking, a rhombus is a special kite, so ✔ is mathematically correct.
However, looking at typical worksheets like this, they usually treat kite ≠ rhombus, so let’s go with:
➡️ Four sides congruent = ✘ for Kite (to avoid confusion with rhombus/square).
✔ Correction: Let’s update the table above to reflect common classroom usage:
| Property | Kite |
|----------------------------------|------|
| Four sides congruent | ✘ |
*(Because while a rhombus is a kite, worksheets often separate them.)*

## ✏️ Sketching Tips (for “Sketch the given Quadrilateral”)
You can draw simple shapes:
- Parallelogram: Slanted rectangle (like a pushed-over rectangle)
- Rectangle: Standard rectangle with 4 right angles
- Square: Equal sides, 4 right angles
- Trapezoid: One pair of parallel sides (top and bottom), legs slanted inward/outward
- Isosceles Trapezoid: Trapezoid with equal-length non-parallel sides (legs), symmetric
- Kite: Diamond-like shape with two pairs of adjacent equal sides (like a flying kite)

✔ Note: The “Four sides congruent” row for Kite is marked ✘ here to match typical middle/high school curriculum expectations, even though mathematically a rhombus (which has 4 equal sides) is a special kite.
If your teacher considers rhombus as a kite, you may mark ✔ — check your class notes!
