It depends on which angle is labelled M.
Let's call the two angles angle 1 and angle 2. We are given that angle 1 and angle 4 form a linear angle and that angle 2 and angle 4 form a linear angle. Because linear angles measure 180 degrees, we arrive at: m<1 + m<4 = 180 m<2 + m<4 = 180. By subtracting the second equation from the first, we get: m<1 - m<2 = 0. And finally: m<1 = m<2. Thus, angle 1 is congruent to angle 2.
D90! It might cost more, but the Megapixel rating is better, and the ratings are MUCH better. Not to mention the D90 has a HIDEF VIDEO OPTION!!!! the only dslr to have it too! get the D90! Seriously! I have it, and i have over 4,000 pictures on it right now. i love the dang thing.!

D90
The Nikon D90 does have plenty of lenses, and is generally regarded as an excellent camera.
Yes, the Nikon D90 Digital SLR has image stabilization.
What is angle 3
Nikon d90 has the capability to shoot video. The D90 is the ONLY DSLR to do that. Also, there's a difference in resolution. I'm not sure what the difference is as far as resolution, but i know there is one. Over all, there's actually tons of differences. I own the D90, and it's great. I've used the D80 though, and it's great too. I think the D90's better, but it's all preference D90's worth the extra money though. BY A LONG SHOT!!!!
