Question

plz ans 1 and 2 q...................................................

Answer 1

use distance formula to calculate distane of p frm a and frm b then equate them i.e (pa)^2=(pb)^2 ; distance formula = root of (x2 - x1)^2 +(y2 - y1)^2 for question 2 asume 3rd vertex p(x,y) then calculate distance between all three pts and equate them u will get two linear eqn and solve them u will get (x,y)
