Question

1. classify the shape based on the following description.

opposite sides are parallel and congruent, and all vertices are right angles.
○ rhombus
○ parallelogram
○ rectangle
○ square

Explanation:

A parallelogram has opposite sides parallel and congruent, but not necessarily right angles. A rhombus is a parallelogram with all sides congruent, but no requirement for right angles. A square is a special case of a rectangle with all sides congruent. The given description (opposite sides parallel/congruent, all right angles) matches the core definition of a rectangle, which includes squares as a subset, but the rectangle is the most accurate general classification here.

Answer:

Rectangle
