triangle AOB is a right angled triangle....(1.5, 2)is the midpoint co-ordinate of AB the co-ordinate of B is (2.5. 0)...

Find the height of point A reached by the the top of the triangle...

Could you show this step-by step please?

Rise over run. Going from 1.5 to 2.5 along the x axis caused the height to go from 2 to zero. Run=1, rise=-2. So going from 1.5 should to zero should raise the point up 3. Top of the triange is at 5.
