3. Peter is in the seat of a Ferris wheel rotating about its center O. The seat is at a point P. He is rotated from P by each of the following rotations. Draw and label his positions after each rotation from P on the coordinate grid.
5. The diagram shows the minute hand of a clock rotating about the center, O of the clock face. The minute hand is initially represented by OP. Point P is at position (3, – 4). Find the position of the minute hand under each of the following rotations.
7. A regular pentagon ABCDE is rotated about its center O, so that its appearance stays the same, but the vertices are rotated to different positions. The pentagon is rotated so that the vertex A moves to the original position of B. Describe two possible rotations, stating each angle of rotation and the direction.
8. P9Q9 is the image of PQ under a rotation about O. Explain, without using a coordinate grid, how you would obtain the position of O by construction. Show your construction clearly.
