Question

A=(7, 1)B(3, -3)are two points if the point (k=1)lines on the perpendicular bisector of AB then the value of k



​

Answer 1

Answer:

let DE cut AB extended at F  

We have BE=EC

angle (BEF)= angle (DEC)

∠(FBE)=∠(ECD)

so triangle CED congruent to BEF ( case ASA)

so EF= ED and CD=BF=AB

∴ inΔ ADF, AE is the median and angle bisector of angle A so triangle ADF is isoceles.

so AD= AF=2.AB => AB= 1/2  AD
