Mathematics is a way of dealing with tasks that involves numbers and equations. The answer of your question is North East because the opposite of Northwest is south east and 90 degree anticlockwise to south east is North East. Trapezoid PQRS, where P (-3,-5), Q (3, -5), R (5,-2), and S (-5,-2) is rotated 90 clockwise about the origin to create trapezoid PQRS. The vector (1,0) rotated +90 deg CCW is (0,1). If we represent the point (x,y) by the complex number x+iy, then we can rotate it 45 degrees clockwise simply Whether rotating clockwise or counter-clockwise, remember to always switch the x and y-values. Math is a challenging subject for many students, but with practice and persistence, anyone can learn to figure out complex equations. The general rule for rotation of an object 90 degrees is (x, y) > (-y, x). Since the rotation is clockwise the hour hand is also rotated clockwise to represent a time that is later than 12:10 pm., the correct time after the rotation of the minute-hand is 12:40 pm. The rule for 90 counterclockwise rotation is (x,y) becomes (-y,x), lets apply the rule to find the vertices of our new pentagon.
