Question

Look at this diagram:

Q
R
S
T
U
V
W
X


If
RT
and
UW
are parallel lines and mRSQ = 122°, what is mTSV?

°

Answer 1

I can’t be sure of the angle relationships from the text alone — I need the picture or a clearer description of how the points are connected.

Could you either
- attach the diagram image, or
- say which points are connected by the transversals (for example: “Q is connected to V and X, R to W, S to U…”), or
- say whether the letters Q,R,S,T are on one line and U,V,W,X on the other and which segments cross the two parallel lines?

If you can’t attach the picture, a short ascii sketch like one of these would work:
- left column: Q R S T right column: U V W X with diagonals Q—V—X and T—U—?
or
- show lines and intersections, e.g. “two parallel horizontal lines; a diagonal from Q down-right meets the upper line at R and the lower at V; another diagonal from T up-right meets them at S and W,” etc.

Once I have the layout I’ll compute m∠TSV and show the reasoning.
