Ruler and Set Square - Precision Measuring Tools for Drafting & Woodworking #3417347 (License: Personal Use)

This illustration shows a standard metal ruler intersected by a steel try square (also called a set square), both fundamental tools in technical drawing, carpentry, and machining. The try square’s stock and blade form a precise 90-degree angle, while the ruler provides linear measurement in inches or centimeters, often marked with fine gradations for accuracy. These tools are indispensable for layout work where dimensional fidelity is critical.
