The first idea that comes to my mind is to use the distance formula.

2. anonymous

your answer is$US=\sqrt{(3-6)^{2}+(3-1)^{2}}=\sqrt{9+4}=\sqrt{13}$

3. anonymous

draw the points on a sheet and you can identify the diagonals.

Why did you choose those pints Syderitic?

okay can you tell what formula i need to use for this problem Find the length of the medians of the triangle whose vertices are A(-1, -2), B(3, 6), and C(1, 0). median to AB = median to BC = median to CA =

6. anonymous

A median is a line segment and you're looking for the lenght of a segment line.

7. anonymous

in the case of a right line you can find its lenght by using the distance formula.
