Question

One of the points that defines a certain quadrilateral is (1,1)(1,1)left parenthesis, 1, comma, 1, right parenthesis. The quadrilateral has rotational symmetry of 90^\circ90 ∘ 90, degrees about the point (-4,-4)(−4,−4)left parenthesis, minus, 4, comma, minus, 4, right parenthesis.

Answer 1

Step-by-step explanation:

There is no questions asked. But given that one of the points that define a certain quadrilateral is (1, 1), and that the quadrilateral has rotational symmetry at 90 degrees about the point (-4, -4). Then the other point is also (1, 1).
