How are the coordinates of the new point found if it is rotated 90á counterclockwise? how many degrees is that equivalent to if the rotation is clockwise?
how are the coordinates of the new point found if it is rotated 180á counterclockwise? how many degrees is that equivalent to if the rotation is clockwise?

The new coordinates of new point if it is rotated by 90 degree counterclockwise by adding pi/2 to the coordinate. It is equivalent to 270 degree if it is rotated clockwise direction. The new coordinates of new point if it is rotated by 180 degree counterclockwise by adding pi to the coordinate. It is equivalent to 180 degree if it is rotated clockwise direction.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
