ACT Math Prep Geometry: Midpoints and Endpoints
In this ACT Math prep video, we cover a classic ACT math problem that shows up all the time on the ACT. You are given the midpoint and one of the endpoints of a segment, and you must find the coordinates of the other endpoint of the segment.
This problem continues to show up on the ACT, mainly because students continue to get it incorrect. In the video, we show three different methods for using the given midpoint to find the missing endpoint.
