In a ΔRST, Z is a point on side ST and SZ = ZT. If ∠RZS = 90 degree and RS = 10 cm, then what is the value of RT?
Answer & explanation
Correct answer: option 2

In \(\Delta \)RZS and \(\Delta \)RZT
\(\angle\)RZS = \(\angle\)RZT = 90
SZ = ZT (Given)
RZ = RZ (common)
By using SAS criteria of similarity,
\(\Delta \)RZS is congruent to \(\Delta \)RZT
Therefore, RT = 10 cm.
