"geometry grade 12"
| |
hi
i was lookin for converse of Hypotenuse-Side theorem on the net . i wasn't able to find it. i spent a full hour but no luck. this theorem is in my book and it makes sense . but how do i prove the converse of it. here is the theorem itself "if the hypotenues and one other side of a right angle triangle is equal to the hypotenues and other side of another right triangle , then triangles r congruent". i think the converse wud be "if 2 right triangles r congrurnt than the hypotenues and one other side of one right triangel is equal to hypotenues and one other side of the other triangle"
now i dono if it makes sense, please help me. n how do i prove the converse by indirect method. |

If two triangles are congruent, their corresponding sides, angles, as well as the perimeter and area and also the corresponding medians, angle bisectors, to mention just a few relevant elements, are equal. |

But what is the converse of the statement: If the hypotenuse and one other side in two right triangles are equal, then the triangles are equal. In my view, the converse is: If two right triangles are equal then their hypotenuse and one other side are equal. What does the third side have to do with that? |

You may be curious to have a look at the old CTK Exchange archive.
