Similar Triangles!!! (Sim Trig)

thingiverse

This is a teaching tool comprised of two similar triangles, perfect for demonstrating similar triangles in math classes. Students can explore numerous activities with the triangles, ruler, paper, and protractor to discover proportional side lengths and congruent angles. As seen in the photograph. Several print settings are required to create the model accurately: select a 3D printer like M3D; ensure Rafts are set to yes for stable printing; set Supports to depends on your desired activity design; and adjust Resolution accordingly, ideally low infill around 20% works well. Notes from previous prints may be helpful – try using green masking tape for improved texture and print stability. Post-printing instructions outline an exercise idea. How it was designed: these similar triangles were created with 123D Design and Blender software. Project name: Sim Trig! Objectives: This tool aims to provide an engaging way for teachers to teach students about similar triangles through interactive hands-on activities tailored for kinesthetic learners who benefit from physical representations of lessons, remembering concepts more effectively when having something tangible to compare them to. Audiences: suitable for any grade level studying similar triangles but most likely used in high school or grade 8. Preparation: Students should be familiar with what similar triangles are prior to using these activities to reinforce that understanding. Various materials may be needed depending on the chosen activity, with basic tools such as a ruler, protractor, pencil, and paper required for many exercises. Steps: one potential exercise involves taking a piece of paper and the two similar triangles. Get students to draw several variations in size and orientation of the smaller triangle onto the paper using tracing methods.
