Scholastic Clear Triangles - Straight Edge

Pacific Arc Clear Scholastic Drafting Triangles are durable, transparent triangles designed for accurate technical drawing, layout work, geometry, and drafting. The fully clear polystyrene construction allows you to see the drawing surface underneath, making it easier to align angles and position lines precisely.

Each triangle includes a straight edge for drawing clean, straight lines with pencils, technical pens, and markers. Available in both 30°/60° and 45°/90° configurations, these scholastic triangles are ideal for students while remaining durable enough for classroom, studio, and professional use.

Features

• Fully transparent design provides a clear view of the drawing surface underneath
• Durable, lightweight polystyrene construction
• Straightedge helps produce clean, straight lines
• Available in 30°/60° and 45°/90° triangle styles
• Available in 4", 6", 8", 10", and 12" sizes
• Suitable for students, educators, architects, engineers, and designers
• Ideal for technical drawings, schematics, geometry, and architectural layouts

30°/60° Drafting Triangle

The 30°/60° triangle is commonly used for architectural drafting, engineering drawings, isometric layouts, and technical illustrations. It provides accurate 30-degree, 60-degree, and 90-degree reference angles.

45°/90° Drafting Triangle

The 45°/90° triangle is ideal for drawing perpendicular lines, square corners, diagonal layouts, and accurate 45-degree angles. It is a versatile choice for general drafting, geometry, and design work.

Available Sizes

Pacific Arc Clear Scholastic Triangles are available in a variety of sizes for different drawing formats and applications:

• 4-inch drafting triangle
• 6-inch drafting triangle
• 8-inch drafting triangle
• 10-inch drafting triangle
• 12-inch drafting triangle

Smaller triangles are convenient for student kits, notebooks, and portable drawing boards. Larger triangles provide longer working edges for architectural plans, engineering drawings, and full-size drafting projects.

Common Uses

• Student drafting kits
• General drawing and design work

Why Use a Clear Drafting Triangle?

A transparent drafting triangle makes it easier to see existing lines, measurements, and drawing details beneath the tool. This improved visibility helps with accurate placement and alignment while reducing the need to lift and reposition the triangle repeatedly.
