About This Worksheet
This hard-level worksheet contains 27 problems designed for 10th Grade students practicing rectangles, rhombi & squares. Hard worksheets feature challenging problems including multi-step questions, missing values, and real-world applications to push students further.
Rectangles, rhombi, and squares are the most common shapes in architecture, art, and everyday life. Understanding their special diagonal and angle properties allows students to solve practical measurement problems and to prove geometric theorems about symmetry and equal parts.
- Apply the special properties of rectangles (congruent diagonals), rhombi (perpendicular diagonals, bisected angles), and squares
- Determine whether a parallelogram is a rectangle, rhombus, or square given specific conditions
- Solve problems using the diagonal properties of each special parallelogram
- Calculate diagonal lengths of rectangles using the Pythagorean Theorem
- Classify a quadrilateral on the coordinate plane using slope, distance, and midpoint formulas
How to Solve: Worked Example
- The diagonals of a rhombus bisect each other at right angles, giving legs of 5 and 12.
- Side = √(5² + 12²) = √169 = 13.
- Area of a rhombus = (d₁ × d₂)/2 = (10 × 24)/2 = 120.
