{"product_id":"helix-locking-compass-and-protractor-set","title":"Locking Compass \u0026 Protractor Set","description":"\u003cp\u003eGeometry assignments demand tools that actually work when you need them. This set pairs a shatter-resistant 6-inch protractor with a locking compass that maintains its radius setting through repeated use, no slippage mid-circle that forces you to start over. The compass mechanism locks securely once you set your measurement, whether drawing precise circles for technical diagrams or constructing geometric proofs.\u003c\/p\u003e\n\u003cp\u003eClear translucent plastic lets you see your work beneath the protractor as you measure angles, eliminating the guesswork that comes with opaque tools. Both pieces resist the drops and impacts that inevitably happen when shuffled between classroom, locker, and backpack. Helix designs these instruments for students who need reliable performance without the cost of professional-grade equipment.\u003c\/p\u003e\n\u003cp\u003eThe straightforward construction focuses on the fundamentals: accurate measurement, durable materials, and tools that function consistently across algebra, geometry, and trigonometry coursework. Perfect for students building their first complete geometry toolkit or replacing worn instruments that no longer hold settings properly.\u003c\/p\u003e","brand":"Helix","offers":[{"title":"2 pieces","offer_id":47982995472613,"sku":"39433","price":3.92,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.texasart.com\/products\/helix-locking-compass-and-protractor-set","provider":"Texas Art Supply","version":"1.0","type":"link"}
