O A'(9, -7).B'(3, - 8).0' (7, - 10) O A'(-7, 9).B'(-8, 3).C' (-10, 7) O A'(-9, - 7).B' (-3, - 8).0'(-7, - 10) O A'(7, - 9).B'(8, - 3),0'(10, - 7) 2. BC has endpoints B ( 4, 6 ) and C'( 9, 7 ). Find the coordinates of the vertices of the segment if it is rotated " counter-clockwise about the origin, O B'(-6, 4 ), C' ( -7, 9 ) O B' ( 4, - 6). C'(9,- 7 ) O B'(6, -4).C'(7, - 9 ) O B'(-4, - 6).C'(-9, - 7)3. Tell whether the transformation of the polygon containing a letter onto the polygon without a letter is a rotation about the origin. If so, give the angle and direction of rotation. y 4. Tell whether the figure has rotational symmetry. If so, give each angle and direction of rotation that produces rotational symmetry.5.
