If two sides of a triangle are congruent, the angles opposite those sides are congruent. True/False

False

Step-by-step explanation:

This is not true because the two sides of a triangle are not congruent

False

Step-by-step explanation:

If angles opposite those sides are congruent, then two sides of a triangle are congruent. ... The Converse of the Isosceles Triangle Theorem states: If two angles of a triangle are congruent, then sides opposite those angles are congruent.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
