Please try to help me out as much as possible -- this homework is due tomorrow. Thx :-)
<=angle
T=perpendicular to (when upside down)
(Write proof in two-column form)
Given: <JMK=<LMK; segment MK T plane P
Prove: segment JK = segment LK
There is a plane (P) and there are two obtuse triangles on top of the plane, with one of their legs the same. One triangle is triangle JMK, and the other is triangle LMK.
I hope this is enough, but it's from the textbook "Geometry" from McDougal Littell/Houghton Mifflin companies, and written by Ray C. Jurgensen, Richard G. Brown, and John W. Jurgensen. It's on page 160, number 10 on the Chapter Review for Chapter 4.
If you look on hotmath . com / help / homework / geometry-library.html, it's the 6th book down from the top on the left side. :-)
To make things more clear, the triangles' sides that are the same are the sides directly above the obtuse angle.
THANK YOU SO MUCH!!!
