C-08-Q121mediumsingle_mcq

In Exercise 8.2 Q5, two chords $AB$ and $CD$ intersect at $E$ . Then $\triangle AED$ and $\triangle BEC$ are—

acongruent
bequiangular (similar)
cperpendicular
dunrelated

ব্যাখ্যা

In $\triangle AED$ and $\triangle BEC$ the vertically opposite angles at $E$ are equal, and the angles subtending the same arcs are equal as inscribed angles in the same segments. With equal corresponding angles the triangles are equiangular, hence similar.
