Hi! Please help me I only have today to finish this! I just want to know the basics. Please hep me solve this :) I added a diagram! NO is the base of the isosceles triangle MNO. The perpendicular from N to Mo meets MO at A. Prove that the measure of angle ANO is half the measure of angle NMO. Prove this using two column proof. (Hint: draw altitude MB)

>>O is the base of the isosceles triangle

A point cannot be the base of a triangle. It should be a segment.
Is it segment NO, segment MO, or something else that is the base of the isosceles triangle?

Where is point B?

If you have a diagram, please post it. Thanks.

anonymous · Answer

Point B is a point on NO and is a altitude from point M

anonymous · Answer

I think I can solve it now, thank you again.

directrix · Answer

I am wondering if the legs of the isosceles triangles are MN and MO.

Attached is the diagram with more known info marked.
