Understand the problem

A chord is a segment that connects two points on a circle.

Step-by-step solution

To determine the truth of the statement, we must consider the precise definition of a chord in the context of circle geometry:

A chord is specifically defined as a line segment whose endpoints both lie on a circle. This segment connects two distinct points on the circumference of the circle. This definition highlights the role of the chord as a geometric entity within the circle.

Given this definition, we evaluate the statement: "A chord is a segment that connects two points on a circle."

The provided statement accurately describes the nature of a chord. The endpoints of the segment must be on the circle, thus aligning perfectly with the standard definition of a chord.

Therefore, the statement is True.

Final Answer

True

Key Points to Remember

Essential concepts to master this topic
  • Definition: A chord connects two points on a circle's circumference
  • Identification: Both endpoints must lie exactly on the circle boundary
  • Verification: Check that segment endpoints touch the circle's edge ✓

Common Mistakes

Avoid these frequent errors
  • Confusing chords with other circle segments
    Don't think any line touching a circle is a chord = wrong identification! A chord specifically needs both endpoints ON the circle, not just touching it. Always ensure both endpoints lie exactly on the circumference.

FAQ

Everything you need to know about this question

What's the difference between a chord and a diameter?

+

A diameter is a special type of chord that passes through the center of the circle. All diameters are chords, but not all chords are diameters!

Can a chord be outside the circle?

+

No! A chord must have both endpoints on the circle. If any part extends outside, it's not a chord but a different type of line segment.

Is a chord the same as a radius?

+

Not at all! A radius goes from the center to one point on the circle, while a chord connects two points on the circumference without necessarily touching the center.

What's the shortest possible chord?

+

Technically, there's no shortest chord since you can make them infinitely small. However, the longest chord is always the diameter!

How do I know if two points make a chord?

+

Simply check: Are both points on the circle's edge? If yes, then the line segment connecting them is definitely a chord.
