Similar to the limits-without-lhopital tag, we should have a geometry-without-trigonometry tag. Many times the OP posts a problem hoping to find an "elementary" solution but the answers use trigonometry. The OP may understand trigonometry but wants a pure geometrical solution or he may be in midd...

Proposal: create "geometry-without-trigonometry" tag Similar to the limits-without-lhopital tag, we should have a geometry-without-trigonometry tag. Many times the OP posts a problem hoping to find an "elementary" solution but the answers use trigonometry. The OP may understand trigonometry but ...
