# Thread: NEED help for these fill-in problems!!

1. ## 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, $\displaystyle \Delta TUY = \Delta ACB$ and $\displaystyle AY=BH$.

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

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

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