Since ABCD is a square, and AC is the diagonal of the square, therefore, then, angle BAC would be Option B. 45°
<h3>What is square?</h3>
A square is known as a quadrilateral with four interior angles of 90° each, and four equal sides.
Properties of a square include
- The interior angles are equal to 90°
- All the sides are congruent or equal
- The opposite sides are parallel
- The diagonals of the square bisect each other at 90 degrees
- The two diagonals are equal
Angle BAC is half the angle of the diagonal
= 90/2 = 45°
Thus, since ABCD is a square, and AC is the diagonal of the square, therefore, then, angle BAC would be Option B. 45°
