## Long description

Grand GR-853T is a 13 cm school triangle designed for drawing and measuring straight lines and angles. This compact ruler set square offers a stable, straight edge for pencils and pens and is intended for everyday classroom use. Its size fits standard pencil cases and provides a simple, practical tool for geometry, technical drawing and general measuring tasks.
Advantages
The rigid triangular shape ensures consistent alignment and accurate guidance when sketching lines or transferring measurements. Made with a smooth edge, the ruler reduces pencil slippage and supports clear, precise strokes. Its compact 13 cm length balances portability with enough working surface for typical school assignments, and the lightweight construction makes it easy to carry between classes.
Suitable for
School geometry and mathematics exercises

Pupil pencil cases and portable study kits
Key specifications
Form: triangular set square
Length: 13 cm (hypotenuse/maximum edge)
Material: rigid transparent or translucent plastic (smooth edge)
Edge type: straight, smooth for pencil and pen guidance
Use: manual drawing and measuring of straight lines and right/standard angles
Portability: compact and lightweight, fits most pencil cases
How to use
Place the set square on the drawing surface with the chosen edge aligned to the reference point or existing line. Hold the triangle firmly with one hand to prevent movement and draw along the edge with a pencil or pen for a straight line. For angle construction, align one edge with the baseline and draw along the adjacent edge to form the required angle. Use the hypotenuse or shorter legs depending on the length needed; the compact size is suitable for small-format paper and notebooks.
Usage recommendations
Store the set square flat in a pencil case or protective sleeve to avoid edge chips and warping. Clean gently with a soft cloth to remove graphite or ink residues. For more precise technical work, use with a straightedge or alongside a protractor when exact angle measurement is required.
