Lemmas In Olympiad - Geometry Titu Andreescu Pdf [work]
be four points forming an orthocentric system (where each point is the orthocenter of the triangle formed by the other three). Consider any pair of circles drawn on segments of these points as diameters.
Many lemmas boil down to finding cyclic quadrilaterals. Always search for pairs of opposite right angles or equal angles subtending the same segment.
Never read a geometry solution passively. Draw the diagrams yourself using a compass and straightedge, or digital software like GeoGebra. Try to anticipate the next step before reading it. The "Build-Up" Technique
