Angle at the centreConsider the two angles which stand on this same chord/Arca) Central Angle subtended by the minor arc. b) Angle subtended by major arc
Chord
What do you notice about the angle at the circumference?
It is half the angle at the centre
We say “If two angles stand on the same chord, then the angle at the centre is twice the angle at the circumference”
