Question

in given triangles parts shown by identical marks are congruent state the test of congruency and remaining parts​

Answer 1

Congruency simply means to have the property of completely overlaping within two similar figures,,if they show congruency ofcourse they have to be similar with each other..

As in your above figure u have two triangles lying on similar base DC also the two angles which are marked are also same..

Now if u have to prove these triangles congruent u can find the side or may be angle to prove them congruent..The property may be applied can be SAS and ASA..

But now as u don't give any clue u can find out the congruency of figures by simply overlapping..if they overlap they are congruent but if they don't than they are not congruent..

Hope it helps u..
