figure abcd is a parallelogram with point c (3, −2). figure abcd is rotated 90° counterclockwise to form figure a′b′c′d′. what coordinate would be the output for point c'?

the correct answer is (2,3)

Step-by-step explanation:

the point starts in the 4th quadrant, if youre moving counterclockwise, the new point would be in the 1st quadrant.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

hello i might . what do you need.
