Prove that each of the angles of a square is a right angle and each of the four sides is of same length.

In the given figure, $ABCD$ is a square. Find the measure of $\angle CAD$.

Look at the below rectangle and find how many squares are there in each row? (Horizontal and vertical lines are $1$ centimetre apart)

(If the answer is $X$ squares, then write $X$ in the given box.)
