Question

which of the following describes a chord? a. a continuous portion of the circles circumference b. a segment that is outside the circle c. a segment that touches the circle at one point d. a segment with both endpoints on the circle which tool is essential for constructing a tangent line from a point outside the circle? a. compass b. triangle c. ruler d. protractor if two tangent segments are drawn to a circle from an external point, what can be said about the segments? a. they form a right angle b. they are parallel c. they are perpendicular d. they are equal in length

Explanation:

1. A chord is defined as a line - segment with both endpoints on the circle. Option a describes an arc, option b is not a standard circle - related term for this context, and option c describes a tangent.
2. To construct a tangent line from a point outside the circle, a compass is essential for creating equal - length segments and right - angled constructs during the construction process.
3. If two tangent segments are drawn to a circle from an external point, by the tangent - segment theorem, they are equal in length.

Answer:

1. d. A segment with both endpoints on the circle
2. a. Compass
3. d. They are equal in length
