Geometry

Question Analysis:
This question requires recognizing the conditions for a shape to be a parallelogram.
The main focus is on diagonal bisection.

Key Concept Explanation:
A quadrilateral is a parallelogram if and only if the diagonals bisect each other.

Step-by-Step Solution:
Given PT = TR and QT = TS → both diagonals are bisected.
Therefore, PQRS must be a parallelogram (no need to check angles or side lengths).

Option Analysis:
A. Square – needs equal sides and 90° angles (not guaranteed).
B. Rectangle – needs right angles (not given).
C. ✅ Correct – diagonal...
