Answer 1

Answer:

please+ 2 \times 18 \div 4

Answer 2

Given:-

• If two chords are equally Inclined to the diameter, i.e, <LAO = <MAO

• OL Perpendicular to AB & OM Perpendicular to AC.

To Prove :-

• AB = AC

Concept used :-

• if the chords are equidistant from centre then the chords are equal.

Now,

• In ∆OAL and ∆OAM

• → <OAL = <OAM ( given)

• → <OLA = <OMA = 90° ( given)

• →AO = OA ( Common sides )

• Thus, ∆OAL ≈ ∆OAM by ASA Congurency Criteria.

• Therefore, By concept, AB = AC.

Hence, Proved!
