predict what will happen to the coordinates of a point as the point rotates counterclockwise (ccw) about the origin
to produce point y. choose rotation angles of 90' 180°. 270", and 360" express your answers in terms of xandy. be
sure to watch your signs

enter the numerical coordinates of the vertices of quadrilateral abcd in the table. (point a has been done for you.) then
predict the numerical coordinates of the vertices of quadrilateral abcd'as the figure rotates about the origin through
these angles: 90", 10" 270" and 360°

½ r² ∅
the area of a sector of a circle is ½ r² ∅, where r is the radius and ∅ the angle in radians subtended by the arc at the centre of the circle. so in the below diagram, the shaded area is equal to ½ r² ∅ .
