Question

Which of the following is/are true?

• A. In a circle, if two chords are equal in measure, then their corresponding minor arcs are equal in measure.
• B. If two arcs of a circle are equal, the subtend equal angles at the centre.
• C. Circles having different radii are similar.
• D. Two tangents can always be drawn to a circle from any point outside the circle, and these tangents are equal in length.

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A

In a circle, if two chords are equal in measure, then their corresponding minor arcs are equal in measure.

B If two arcs of a circle are equal, the subtend equal angles at the centre.
C Circles having different radii are similar.
D Two tangents can always be drawn to a circle from any point outside the circle, and these tangents are equal in length.

1. In a circle, if two chords are equal in measure, then their corresponding minor arcs are equal in measure.

2. If two arcs of a circle are equal, the subtend equal angles at the centre.

3. Circles having different radii are similar but not congruent.

4. Two tangents can always be drawn to a circle from any point outside the circle, and these tangents are equal in length.
