✌✌HELLO SISO✌✌
A perpendicular bisector is a line which cuts a line segment into two equal parts at 90°. So AC to be a perpendicular bisector of BD it must not only cut it at 90° (which it does) but also cut it into two equal parts. Now, in order AC to cut BD into two equal parts right triangle ABD must be isosceles, which, as it turns out after some math, it is not.
Complete solution:
In triangle ABC, if BC = 3 and AC = 4, then what is the length of segment CD?
question.
a perpendicular bisector, the bisector always crosses the line segment at right angles
If any line cuts another line at 90 then it should be a perpendicular bisector right - i.e it divided the line segment into equal halves at 90 ?
So here BC should be the perpendicular bisector and the AC=CD=3 right ?
Please let me know what am missing here.
I do understand the explanations in the other thread mentioned,but can someone clarify as to why AC is not the perpendicular bisector ?

A. 3
property: perpendicular to the hypotenuse will always divide the triangle inwo triangles with the same ACB and DCA (which are also similar to big triangle ABD). Now, in these three triangles the ratio of the corresponding sides will be equal (corresponding sides are the sides opposite the same angles marked with red and blue on the diagram).
