这样三角关系是 congruent。( 为什么?) 跟着那 de = DF。同样地,分克 = DF。 翻译结果3复制译文编辑译文朗读译文返回顶部 所以三角形是一致的。(为什么?)它跟随,DE = DF。同样,DG = DF。 翻译结果4复制译文编辑译文朗读译文返回顶部 因此三角是一致的。(为什么?)因而断定DE = DF。同样, DG= DF。

To prove that two right triangles are congruent if the hypotenuse and one side of one triangle are respectively equal to the hypotenuse and one side of the other triangle, we can follow these steps:1. Identify the Triangles: Le
Which of the following pairs of triangles are congruent ? Also state the condition of congruency in each case : (iv) In DeltaABC and DeltaDEF, AB=EF, BC=
In this article, we discuss whether a single congruent number t can have two (or more) distinct corresponding triangles with the same hypotenuse. We describe and carry out computational experimentation providing evidence that this does not occur.Lowry-Duda appendix by Brendan Hassett, David...

aBecause triangles BEF and AC are similar, and since BE is half of BA, it follows that EF is half of AC. Also, because triangles DHK and DAC are similar and DH is half of DA, it follows that HK is half of AC. Therefore HK = EF and triangles DEF and DHK are congruent. (Why?
