Question

On graph paper or using a drawing program, such as GeoGebra, plot three points on the coordinate plane.
Label each point with a letter and its corresponding ordered pair.
Draw segments between the points to form a triangle.
Use the midpoint formula to find and plot the midpoint of each segment. You must show your work.
Draw the three medians of the triangle.
Draw the centroid – the point of intersection between all three medians.
Estimate the ordered pair of the centroid.
part 2
Use the distance formula to find the length of each side of the triangle.
Classify your triangle

Answer 1

How many medians are needed to find the centroid? Why?
How did the distance formula help you determine if the triangle is scalene, isosceles, or equilateral?

Answer 2

You could at least show us what you've done so far. Nobody is going to just do all of this for you.

Answer 4

Make sure you choose 3 points that fall on the grid lines. You're going to have to find midpoints and it will be a pain if some of your coordinates are not integers. Your point C doesn't look like it's falling on the grid lines like your A and B. Move C. Also don't forget to label each point with its coordinates....like A should have a (2,2) next to it.
