Question

An architect is designing a new windmill with four sails. In his sketch the sails center of rotation is the origin (0,0) and the top of one sails point T, has a coordinates (6,-2). He wants to make another sketch that shows the windmill after sails have rotated 180* degrees about their center of rotation. What would be the coordinates of T?

Answer 1

A 180 degree rotation would make you turn (x, y) into (-x, -y), so you would turn (6, -2), into (-6, 2).

Hope this helps! :)
