(1). Mayda is sketching her design for a rectangular garden. By mistake, she has erased the coordinates of one of the corners of the garden. As a result, she knows only the coordinates of three of the rectangle's vertices. Explain how Mayda can use midpoints to determine the unknown coordinates of the fourth vertex of the rectangle.(2 Marks)

(2). How are the formulas for calculating the length of a line segment and the midpoint of a line segment, using the coordinates of the endpoints, the same? How are they different? (4 Marks)
