Draw a Perfect Diamond

About the Perfect Diamond Challenge

The diamond shape — mathematically known as a rhombus — is a quadrilateral with all four sides equal in length. Unlike a square, the classic diamond is oriented with one vertex pointing up and another pointing down, creating acute angles at the top and bottom and obtuse angles on the sides.

What Makes a Perfect Diamond?

• 4 Equal Sides — All edges must be the same length
• Symmetry — Must be symmetric across both vertical and horizontal axes
• Straight Lines — Each side should be perfectly straight, no curves
• Proper Proportions — Classic diamond has height ≈ 1.5× width, with ~60° top/bottom angles
• 4 Clean Corners — Sharp, well-defined vertices

How We Score Your Diamond

• Side Equality (25%) — How equal in length all 4 sides are
• Straightness (25%) — How straight each edge is (no wobbly lines)
• Symmetry (25%) — Horizontal and vertical axis symmetry
• Corner Quality (15%) — Sharp corners at correct positions
• Closure (10%) — How well the shape closes back to the starting point

Diamond vs. Rhombus vs. Square

All three are related! A rhombus is any quadrilateral with 4 equal sides. A diamond is a rhombus oriented point-up. A square is a special rhombus where all angles are 90°. So every square is a rhombus, but not every rhombus is a square.

In our challenge, we score the classic diamond shape with acute top/bottom angles (~60°) and obtuse side angles (~120°) — taller than it is wide.
