Frequently Asked Questions (FAQs)

Unit 13 covers essential circle geometry concepts such as constructing tangents, inscribing and circumscribing polygons, solving problems with chords, and understanding various types of tangents and their constructions.

To locate the center, draw two non-parallel chords of the circle, construct their perpendicular bisectors, and find the intersection point of these bisectors, which will be the center.

Connect the external point to the circle’s center, find the midpoint of this line segment, and draw a circle with this midpoint as the center. The points where this auxiliary circle intersects the original circle are the points of tangency.

To inscribe an equilateral triangle, divide the circle into three equal arcs using a compass, and connect the three points to form the triangle.

Direct common tangents are tangents that touch two circles externally, while transverse common tangents are those that touch the circles internally.
