Number	Statement	Reason
1.	Line RX is perpendicular to line ST	Given
2.	Line RX is congruent to line RX	Reflexive Property of Congruence
3.	X is the midpoint of line ST	Given
4.	Angle RXS = angle RXT	All perpendicular angles are congruent (and equal to 90 degrees)
5.	SX is congruent to TX	Definition of Midpoint (uses line 3)
6.	Triangle SRX is congruent to triangle TRX	SAS Property of Congruence (uses lines 2,4,5)
7.	Line RS is congruent to RT	CPCTC
