There's a garden, using rectangular coord:

0,0

0,5

12,5


. Obviously, a right triangle.




Q:

#1: Where do I draw a horizontal line so that it can divide the triangle into to 2 equal sections. (y=?)

#2. Prove both section's area are equal after drawing the line.

#3. Where else can I draw a horizontal or vertical line to divide this into 2 equal areas?
