Flashcards
Angle subtended by a chord
Angle subtended by a chord
The angle formed by two lines drawn from a point on the circle to the ends of a chord.
Angle subtended by a chord = radius
Angle subtended by a chord = radius
If a chord of a circle is equal in length to the radius, then the angle it subtends at a point on the minor arc is always 60 degrees.
