Problem 55 of 7
Compute the area of triangle with coordinate base-height information base from (0,0) to (8,0), third vertex (4,3).
Using a hint is okay. It just tells the trainer to give you a little more review.

identify perpendicular base-height pair.
Hidden until you reveal it.
Base and perpendicular height must be identifiable on the coordinate grid.
Enter your answer
Your answer is equivalent to the expected form.

Full solution stays hidden until you ask for it.
1. Identify a base segment.
2. Find the perpendicular distance from the third vertex to the base line.
3. Compute one half times base times height.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using a slanted side as height without proving perpendicularity.
