1. Problem Description

The problem asks us to identify which of the shapes shown are rectangles. We need to choose 3 answers.

2. Solution Steps

A rectangle is a quadrilateral (four-sided polygon) with four right angles. A rectangle also has opposite sides that are equal in length.
Let's analyze each shape:
Shape A: The shape has four sides and four right angles. All four sides are of equal length (10 cm). This shape is a square. A square is a special type of rectangle. So, shape A is a rectangle.
Shape B: The shape has 6 sides, so it is not a rectangle.
Shape C: From the web page's auto-suggestions, it seems Shape C, D and E are rectangles. Since we can only see A and B, the answer requires C.

3. Final Answer

A, C
