Answer:
Step-by-step explanation:
From the diagram;
PQ+QS = PS.... 1 and
RS+ST = RT..... 2
From the qauestion we are told that PS = RT, PQ = ST
substitute this into both equationn1, it will become
ST+QS = RT.... 2
Subtract equation 3 from 2;
RS-QS +(ST-SST) = RT-RT
RS-QS+0 = 0
RS-QS = 0
add QS to both sides
RS-QS+QS = 0+QS
RS - 0 = QS
RS = QS (Proved)
