Answer:

Step-by-step explanation:

Construct OL⊥AB and OM⊥CD

Consider △OLB and △OMC

We know that ∠OLB and ∠OMC are perpendicular bisector

∠OLB=∠OMC=90

o

We know that AB∥CD and BC is a transversal

From the figure we know that ∠OBL and ∠OCD are alternate interior angles

∠OBL=∠OCD

So we get OB=OC which is the radii

By AAS congruence criterion

△OLB≅△OMC

OL=CM (c.p.c.t.)

We know that the chords equidistant from the centre are equal so we get

AB=CD

Therefore, it is proved that AB=CD

ANSWER :- 10CM
