ABC is a triangle with B as right angle, AC=5 cm and AB = 4 cm. A circle is drawn with A as centre and AC as radius. The length of the chord of this circle passing through C and B is
Given: AC = radius = 5 cm
AB = 4 cm
DC is a chord passing B and C
In ABC
AC2 = AB2 + BC2
BC2 = 9
BC = 3 cm
CD = 2 BC
= 6 cm
