In the figure, four lines intersect as shown. Which of the following additional pieces of information is sufficient to prove that angle SWR is congruent to angle TVR?
- Angle VTR is congruent to angle TSW.
- Angle VTR is congruent to angle WSR.
- Angle TRV is congruent to angle SRW.
- Angle TSW is congruent to angle WSR.
The correct answer is: Angle VTR is congruent to angle WSR.
is similar to then 
will be congruent to 
To prove they are similar
