Question:

Tangents drawn at the endpoints of a diameter of a circle are:
(a) Parallel
(b) Perpendicular
(c) Intersecting
(d) Coincident

Step-by-Step Solution

Key Concept: Radii at diameter endpoints are in a straight line ($180^\circ$). Tangents are perpendicular to diameter, making consecutive interior angles $90^\circ + 90^\circ = 180^\circ \Rightarrow$ Parallel.

Angles with diameter are $90^\circ$ each $\Rightarrow$ Parallel. [1.0 Mark]
