  1. Use the LINE for the simple short question and the large area for ALL the details.

    1)A ray drawn parallel to the principal axis will reflect  thru the focus

    2)A ray drawn thru the center of curvature will be incident perpendicular to the mirror and reflect off back  thru the center of curvature

    3) A ray drawn thru the focus will reflect off the mirror parallel to the principal axis

    4) All other rays obey the law of reflection

    You use 1-3 to draw the images
