Circle geometry: tangents, chords and cyclic quadrilaterals

1. 1The straight line crossing a circle at two points is known as its :

   1. AChord
   2. BSecant
   3. CTangent
   4. DNone
2. 2The angles between the tangents to a circle from same external point and the radii through the points of contact are :

   1. AComplementary
   2. BComplete
   3. CSupplementary
   4. DNone
3. 3If chords AB and CD of a circle intersect each other at point P , then PA.PC = PB.PD

   1. ATrue
   2. BFalse
4. 4Tangents PA and PB to a circle touch it at points A and B respectively. If O is the centre of the circle, then quadrilateral OAPB is cyclic.

   1. ATrue
   2. BFalse
5. 5Non parallel sides of a trapezium are [blank_start]equal[blank_end] if it is cyclic.

   1. Aequal
