1. PX\[\cdot \]PY=PZ\[\cdot \]PT |
2. PXZ and PTY are similar triangles. |
A) Only 1
B) Only 2
C) Both 1 and 2/1
D) Neither 1 nor 2
Correct Answer: C
Solution :
When two chords of a circle intersect internally, then they are divided in a proportion. i.e., PX. PY- PZ. PT On \[\Delta \]PXZ and \[\Delta \]PTY, \[\angle \]ZPX = \[\angle \]YPT (Vertically opposite angles) \[\angle \]PZX = \[\angle \]PYT (Angles in same segment) \[\angle \]PXZ = \[\angle \]PTY (Angles in same segment) \[\therefore \]\[\Delta \]PXZ \[\sim \]\[\Delta \]PTY Hence, the both statements are correct.You need to login to perform this action.
