Better yet, look for the book – many mirror sites host a 47-problem excerpt legally. Since "47" often refers to a specific page
If you are looking for a comprehensive guide to the theory and problems of this field, Plane Euclidean Geometry: Theory and Problems and skew lines
This includes understanding parallel, perpendicular, and skew lines, as well as the properties of angles such as complementary, supplementary, and corresponding angles.
If the PDF you find solves problem #47 cleanly with a diagram, you have found a gold standard resource.
