单词	similar
释义	similar (of figures) Two geometrical figures are similar if they are of the same shape but not necessarily of the same size. This includes the case when one is a mirror-image of the other, so the three triangles shown in the figure are all similar. For two similar triangles, there is a correspondence between their vertices such that corresponding angles are equal and the ratios of corresponding sides are equal. In the figure, ∠A = ∠P, ∠B = ∠Q, ∠C = ∠R, and QR/BC = RP/CA = PQ/AB. similar triangles
