In the circle given below,let unit, unit and . Then, the area of the triangle (in square units ) is :
Option: 1
Option: 2
Option: 3
Option: 4
To solve this concept, we will use two concepts that we have learnt in class 9 or 10.
The perpendicular from the centre of a circle to a chord bisects the chord.
If two chords of a circle intersect each other, then the products of the lengths of their segments are equal.
PQ and OB are the chords of the circle
Given OA = 1 unit, OB = 13 unit, so, AB = 12 unit
