Mathematics for IGCSE & O level - Circle Theorems (Section 2 - No. 36)
What can you say about the triangles formed when two tangents intersect at a point outside the circle, where the radii meet the tangents?
They are similar.
They are congruent.
They are right-angled but not congruent.
They are not related.
הֶסבֵּר
The triangles are congruent due to the radii, tangents' lengths, and a common side.
