Can someone please explain the Red Part. Why height of C2 will be 1.
Thanks
If vertices of a triangle have coordinates (-2,2), (3,2) and (x,y), what is the area of the triangle?
We have the three points (-2,2), (3,2) and (x,y).
A) |y-2|=1
This tells us that the y coordinate of (x,y) is 1 away from y=2. What does it mean? It means that the point will have a coordinate in the form of (x,3) or (x,1).
Given the base from the points (-2,2), (3,2), that equals 5, in both cases the heigth will be 1. The first two points are on the y=2 line, and the third will be 1 "away" from it, on y=1 or on y=3.
So the area will be the same in both cases \frac{base*height}{2}, the base will not change and the height is 1
