When you sketch out the diagram... two triangles. Since MN=2ML, and MN=N0, then NO=2ML and it also provides that angle LMN is 90 degrees and since it is an isosceles triange, angle LMN = angle LNM and they are both 45 degrees. Triangle LMN has a similar triange sitting on top of it (you can't see it without the diagram), but it contains angle PNL as it's end point. Since angle M = Angle P and they are 90 degrees and since the angle MLN equals the angle ONL from Parallel lines Alternate angles, and the angle zPN (that is in the small similar triangle, that is sitting on top of triangle LMN), is equal to MLN, we thus know that angle OPN=angle LNO and they are 45 degrees. QED : )
Triangle L'M'N' is a dilation of triangle LMN. If the scale factor of the dilation is 1/5, which of the following statements is true? Triangle L'M'N' is a rotation of triangle LMN. Triangle L'M'N' is the same size as triangle LMN.
Line MP bisects <LMN, m<LMP=4x+3 and m<LMN=10x-6. Find m<LMN. I understand how to find adjacent angles and the complement. I don't understand what I am supposed to do? Since it already give you the answer 10x-6, should
