Arcs and AnglesConjectures:
Arcs and AnglesGiven a circle with inscribed angle CAB
The inscribed angle and the central angle are intercepting the same arc.
Arcs and AnglesGiven a circle with inscribed angles P and Q
The inscribed angles P and Q are intercepting the same arc.
Arcs and AnglesGiven a circle with angles inscribed in a semi-
circle
The inscribed angles intercept a semi-circle.
Arcs and Angles
a and c are opposite angles.b and d are opposite angles.
Arcs and AnglesGiven a circle with two parallel secants
Minor Arc AD and Minor Arc BC are in the interior of the two lines
