内接于三角形的矩形的相关问题,为相似三角形性质的运用提供了非常好的素材.创作题目的老师为了让学生思维得到很好发展,在题目形式上,越来越开放,思维凝练度也越来越高.现以几种形式演变来与大家分享题目的精妙.例1我们定义:“四个顶点都在三角形边上的正方形是三角形的内接正方形”.已知:在Rt△ABC中,∠C=90°,AC=6,BC=3.
The problem of intrinsic rectangles intrinsic to triangles provides a very good material for the use of similar triangles. The teachers of the creative subjects have been developing more and more openly in terms of topics, in order to allow students to develop their thinking well. Higher and higher. Now in several forms evolved to share the subtlety of the topic. Example 1 We define: “The four vertices are on the triangle edge of the square is the triangle inscribed square ”. Known: In Rt In ABC, ∠C=90°, AC=6, BC=3.
