To determine if a square is also a rectangle, let's compare the properties of both shapes.
1. Properties of a Rectangle:
- A rectangle has two pairs of opposite sides that are equal in length.
- The angles in a rectangle are all right angles (90 degrees).
2. Properties of a Square:
- A square has all four sides of equal length.
- The angles in a square are all right angles (90 degrees).
Now, let's see if a square satisfies the properties of a rectangle:
- A square has two pairs of opposite sides that are equal (since all four sides are equal, any pair of opposite sides are indeed equal).
- A square has all angles as right angles.
Since a square meets both criteria: it has two pairs of opposite sides that are equal, and all its angles are right angles, a square satisfies the definition of a rectangle.
Therefore, the correct answer to the question "Is a square also a rectangle?" is:
A. Yes
