Question 1.1. when constructing the centroid of a triangle, you need to find the intersection of all three of what type of line?

The centroid is the point where the three medians of the triangle intersect. So, the answer is that the type of all three lines that you need to find the intersection of is median. Each median is the line that joins the midpoint of a side with its opposite vertex. median

Iwould say false, not positive but if prices went up for both stores, technically there will be less buyers?
