22)meaning of inert

Prepare well

for the interview. Mostly on graphics , geometry .Prepare questions like

(for interview)Prove some of the angles in a triangle are 180.Angle in a

half circle is 90.How will you measure hight of building when you are at

the top of the building and if you have stone with you.

Best of luck
