When we rotate a figure and there is no change in the shape of the figure then it has rotational symmetry.

We know that the order of rotation for a square is 4.

Hence, we have $\frac{360}{4} =90^{\circ}$

Thus, the angle of rotational symmetry of square are

$90^{\circ}, 180^{\circ}, 270^{\circ}$

Hence, the minimum angle of rotational symmetry is $90^{\circ}$

Therefore, the minimum angle of rotational symmetry for a square is 90 degrees.

4 0

Is it 90 degrees because all square have a 90 degree angle?

Answer:

All the ordered pairs (a,b) are

(0,5), (2,3), (4,1), (6,8), and (8,6).

Step-by-step explanation:

765ab4 to be divisible by 36, it must be divisible by both 9 and 4.

For any number to be divisible by 4, the last two digits of the number must be divisible by 4.

Here, the last two digits are b4, so as the number b4 is divisible by 4, b can be 0,2,4,6, and 8.

For any number to be divisible by 9, the sum of all the digit of the number must be divisible by 9.

Here, the sum of all the digits, S= 7+6+5+a+b+4=22+a+b.

Now, we have b={0,2,4,6, 8}

For b=0,

S=22+a+0=22+a which is a multiple of 9.
