About This Set
Each of these 25 takes two steps, which is how most Tier 1 heights questions are built: two angles seen from two points, a plane or car timed between two angles, a statue on a pedestal, or a tower seen from the roof of a building. The usual errors are adding the two distances when both points are on the same side (or subtracting when they are on opposite sides), mixing km/h with m/s, and using a slant length where the ground distance is needed. Allow about 25 minutes; 19 or more right means you are ready for Practice Set 3.
