Westcott - Adjustable Triangle

Adjustable Triangle

Draft precise angles from 0 to 90 degrees with traceable circles included

Angle precision matters when you're working through perspective studies or technical drawings that need to be right. This adjustable triangle locks at any angle between zero and 90 degrees, eliminating the need to own multiple fixed triangles or estimate angles by eye. Dual graduation rows on the arc show both the primary angle and its complement simultaneously, useful when you're calculating relationships or checking your work.

Clear acrylic construction lets you see your drawing underneath while you trace, maintaining visual connection with existing linework. The 10-inch length provides enough reach for medium-format drawings while staying manageable on crowded desks. Four built-in circle templates (1/4", 1/2", 3/4", and 1") handle common circular elements without switching tools, from tiny detail work to moderate accent shapes.

The locking mechanism holds angles securely once set, so repeated tracings stay consistent. Architecture students working through axonometric projections, illustrators establishing vanishing points, and designers drafting technical specifications get accurate angle control without the expense and storage demands of a full triangle set.
