在给定的几何图形中,请你找一找与已知角相等的角或与已知三角形等积的三角形有多少个?请你数一数有多少对全等三角形或相似三角形?本文就怎样“找”法才能快与准举例说明如下.
In the given geometry, please find out how many triangles equal to the known corners or equal triangles with the known triangles? How many pairs of equal triangles or similar triangles do you count? How to “find” the method can be quickly and accurately illustrated as follows.
