 Apr14 awarded Tumbleweed Apr7 asked trigonometry - find coordinates of inner triangle after rotation Mar4 awarded Autobiographer Jun28 awarded Supporter Oct10 comment geometry triangles side-side-side | prove my teacher she is wrong? Thanks for everything, now I understand much more about it. I had learned a lot from u guys. Thanks again Oct10 comment geometry triangles side-side-side | prove my teacher she is wrong? I choose this answer since it helped me the most and had a lot of information. Thank you everybody else that participated and tried to help. Oct10 awarded Scholar Oct10 accepted geometry triangles side-side-side | prove my teacher she is wrong? Oct10 comment geometry triangles side-side-side | prove my teacher she is wrong? thanks for your time and effort. I still have one more question, since the bases are congruent, and the Middle line is congruent, it means the triangle has the same height right? So if that's is right, wouldn't the Angle on the sides be the one deciding the length of the the line on the sides? Like what i mean is kind of hard to explain. The triangle itself is given that it has two congruent lines and one congruent Angle which is on the external sides of the triangle so my hypothesis is that this angle will decide the size of these lines... sorry if i confused you guys. Oct10 comment geometry triangles side-side-side | prove my teacher she is wrong? My point is that, the side lines, the most- right and most- left are the ones deciding the position and how high the middle line will get. It is the place they meet, and since both bases are congruent Then the side lines should be congruent too. Sorry if its hard to understand. Its pretty hard to explain too. Anyways i have to go to class. I will return in about 40 mins. Thanks everybody for putting effort into this!

First of all thanks for the welcoming. Now sss means sidecside side congruence and her opinion is that there is not enough info to decide if the last line is congruence or not. And the middle line bisect the base Oct10 asked geometry triangles side-side-side | prove my teacher she is wrong?
