Becky is writing a coordinate proof to show that the diagonals of a parallelogram bisect each other. She starts by assigning coordinates as given. Drag and drop the correct answer into each box to complete the proof. Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse. The coordinates of point C are (Response area, c). The coordinates of the midpoint of diagonal AC¯¯¯¯¯ are ​(a+b2, c2)​ . The coordinates of the midpoint of diagonal BD¯¯¯¯¯ are (Response area, c2). AC¯¯¯¯¯ and BD¯¯¯¯¯ intersect at point E with coordinates (a+b2,Response area).. By the definition of midpoint, AE¯¯¯¯¯≅Response area and Response area≅DE¯¯¯¯¯. Therefore, diagonals AC¯¯¯¯¯ and BD¯¯¯¯¯ bisect each other.
