Printable worksheet with answer key
-
A line that touches a circle at exactly one point is a:
- 1 Tangent
- 2 Chord
- 3 Secant
- 4 Radius
-
A tangent to a circle is perpendicular to the:
- 1 Radius at the point of contact
- 2 Diameter parallel to it
- 3 Chord
- 4 Another tangent always
Show answer
Correct answer: Radius at the point of contact
The tangent is at right angles to the radius at the contact point.
-
The perpendicular from the centre of a circle to a chord:
- 1 Is a tangent
- 2 Bisects the chord
- 3 Is parallel to it
- 4 Is equal to the chord
Show answer
Correct answer: Bisects the chord
It divides the chord into two equal parts.
-
Tangents drawn to a circle from an outside point are:
- 1 Perpendicular
- 2 Parallel
- 3 Different in length
- 4 Equal in length
Show answer
Correct answer: Equal in length
Two tangents from the same external point have equal lengths.
-
The angle in a semicircle is:
- 1 45 degrees
- 2 180 degrees
- 3 90 degrees
- 4 60 degrees
Show answer
Correct answer: 90 degrees
An angle inscribed in a semicircle is a right angle.
