Dear Eshita,

The new CM would depend on the exact coordinates of the triangle. Basically once you have the coordinates you can calculate it's centroid and that is where the CM of triangle is, say it is (x1,y1). Then also calculate the area to calculate the mas of triangle, say it is M1. Figures coordinates say are at (x0, y0) and mass is M0 then 

(x0, y0) = -M1 (x1, y1) / M0

supposes you are running fast in a field when you suddenly find a snake in front of you. You stop quickly. Which force is responsible for your deceleration? what is it’s direction?
Friction is responsible for deceleration. It’s direction is opposite to your initial direction of motion.
