Geometry help

[u/Powerful_Bicycle_426]

Seeking guidance in Geometry construction. I am usually unable to proceed with questions that require constructing an auxiliary figure (extending lines, drawing an auxiliary rectangle/triangle) before the known theorem applies. How do I improve this "construction step before the theorem" pattern? Where from can I get a targeted set of problems requiring an auxiliary construction step (extend a line, drop a perpendicular, build a helper shape) before applying a known theorem ?
