- 1—Base angles of an isosceles triangle formed from the radii of a circle are equal.
(Base <'s isos. Triangle, = radii) - 2—The angle at the centre is twice the angle at the circumference on the same arc.
(< at centre)
- 3—The angle in a semi-circle is a right angle.
(< in semi-circle)
- 4—Angles on the same arc are equal.
(<'s on same arc)
- 5—Opposite angles of a cyclic quadralateral add to 180 degrees.
(Opp. <'s, cyclic quad)
- 6—The exterior angle of a cyclic quadralateral is equal to the interior opposite angle.
(Ext. <, cyclic quad)
- 7—The angle where the radius meets the tangent is 90 degrees.
(Tgt. Perpendicular Rad)
- 8—Tangents from a point to a circle are the same length.
(Equal tgt)
- 9—The perpendicular from the centre to the chord bisects the chord.
(Perpendicular from centre to chord)
- 10—The exterior angles of a polygon add to 360.
(Ext. < sum of polygon)
- 11—The interior angles of a polygon:
sum= 180(n-2), Where n is the number of sides.
(Int. < sum of polygon)
- 12—Each angle in an equaliteral triangle is 60 degree.
