A triangle has corners A, B, and C located at #(2 ,5 )#, #(7 ,4 )#, and #(2 ,3 )#, respectively. What are the endpoints and length of the altitude going through corner C?
1 Answer
The altitude basis coordinates over the side
Explanation:
Given
A direction perpendicular to
Example:
The vector
So the altitude straight is given by
The intersection point is obtained solving for
The altitude basis in side
