An irregular parallelogram rotates 360° about the midpoint of its diagonal. how many times does the image of the parallelogram coincide with its preimage during the rotation? 2

Since parallelogram is irregular, its diagonals are not equal. Then the first time when the rotation image coincides with the preimage will be when the angle of rotation is equal to (then one half of diagonal lies on the another half of this diagonal) and the second time when the angle of rotation is equal to (when the image takes the initial position).

As you know john locke said he wanted life liberty and the pursuit of happiness so thomas jefferson was inspired about what john locke said so thomas jefferson wrote the declaration of independence for people to be free for people to be happy

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
