    Exclamation NEED help for these fill-in problems!!

    these are some problems I had trouble with. No diagrams were provided, and I tried my best to rewrite them accurately. Please help?

    1. YA is an altitude of triangle TUY. If A does not lie on TU, then triangle TUY must be a(n) _____ triangle.


    2. In triangle RST, if M is the midpoint of RS, then TM is a(n) of ______triangle RST.


    3. In a plane, XA=XB, YA=YB, ZA=ZB, and Z, A, B are collinear, then line XY is perpendicular to AB at Z. What theorem makes this statement true?


    4. To show triangle DEF is congruent to triangle GHK by the SSS postulate, you must first show that ______, _______, and ________.

    1. Obtuse; In this diagram, \Delta TUY = \Delta ACB and AY=BH.

    2. This is just a vocab question. I forget the term, but it should be in your book somewhere.

    3. AXBY is a kite with Z as the midpoint of AB. XY and AB are the diagonals of the kite. A kite's diagonals always intersect perpendicularly at Z.

    4. DE\cong GH,  EF\cong HK, and FD\cong KG.
