1 If PQ = PQ, then PQ - PO 2 If K is between and L, then K + KL - JL
2. FE EF
4 IF RS = TU, then RS + XY = TU + XY
3. IF AB-DE, then DE - AB
6. IF Y' is the midpoint of Vz, then XY = YZ
1 1 FC. Hi and I - JK . then KG UK
& IFAB+CD= EFCD, then 18 = 0
IF PO+ RS - TY and RS - WX, then
PQ+ WX = TV
10. If LP = PN, and LP, and are collinear,
then P is the midpoint of IN
11 IF UT = UV, then UV-UV
12. IT CD + DX = CE, then CD=CO-DR
