Recall that the Angle-Angle Similarity Theorem for triangles states that if 2 angles of one triangle are congruent to 2 angles of another triangle, then those triangles are similar. (For an illustrative proof of this theorem, go to https://tube.geogebra.org/m/Q8EYTUK2).
Yet does the same hold true for quadrilaterals? That is, if 3 angles of one quadrilateral are congruent to 3 angles of another quadrilateral, can we claim that those two quadrilaterals are similar?
