Geometry

Question Analysis:
This question evaluates understanding of parallel sides and diagonal congruence.
The main focus is narrowing down quadrilaterals with these traits.

Key Concept Explanation:
Rectangles & squares: Both have two parallel sides and congruent diagonals.
Rhombus: Parallel sides but diagonals are congruent only if it’s a square.

Step-by-Step Solution:
Identify quadrilaterals with two parallel sides (parallelograms family).
Note that congruent diagonals occur in rectangles and squares.
Square is a subset of rectangles, so both fit.

Option Analysis:
A. Incorrect – Rhombus diagonals aren’t necessarily congruent.
B. Partially correct – Rectangles qualify, but squares do too.
C. Partially correct – Squa...
