I really need help if any one knows geometry please try and help and answer these few questions Thank you!

Segment CR.

Step-by-step explanation:

We have been given an image of a triangle. We are asked to find the segment that is altitude to segment AB.

We know that the altitude of triangle is the perpendicular drawn from a vertex of triangle to opposite side.

We can see that vertex opposite to segment AB is . We can see that there are two lines drawn from vertex C that are segment CR and CN.

We have been given that points L, M and N are midpoints for our given triangle. We know that segment that is midpoint of triangle is known as median of triangle, therefore, CN is not a correct choice.

We can see that segment CR is perpendicular to segment AB, therefore, option B is the correct choice.
