By which angle measures can the square be rotated so it maps onto itself?
select each correct answer.
45°
60°
90°
135°
180°
270°

The correct answers are:

90°, 180° and 270°

Explanation:

Squares have rotational symmetry at 90°.  This can be found by dividing the number of degrees in a circle, 360, by the number of sides, 4:

360/4 = 90

This means that at all multiples of 90, the square will rotate onto itself.  This means that 90, 180 and 270 are all correct.

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.
