Question

in a circle with centre P, chord AB is drawn of length 13 cm,
seg PQ I chord AB, then find ((QB).​

Answer 1

A circle of centre P is drawn,

Chord AB is drawn of length 13cm as shown in figure. Let Q is the point on AB in such a way that PQ ⊥ AB.

we know, the chord is bisected by a line passing through centre and perpendicular upon it. here,

chord AB is perpendicular upon PQ.

so, AQ=QB=

AB

⇒AQ=QB=
