    TRIANGLE ANGLES AND LINES

    OK I need help on this and it would help if you explained it and made it as simple as you possibly could.

    For Each triangle, name the included angle between the pair of sides given.

    Triangle MAT : Line MT and Line TA.

    Triangle CDA: Line CA and line Dc.


    I really need help on this. It might be really easy and i might be thinking to hard here....

    you don't have to answer this bottom part just something i need a little help on.
    Also if Line AB is Parellel to Line DC what thm or post do you use to find if they are congruent?

    what point do the line segments have in common? that would be the vertex point of your angle.

     Triangle CDA: Line CA and line Dc.

    same idea here.

    lines are not congruent.

    O and lines are congruent if they're parallel aren't they?
