  • Cyclic Quadrilaterals 1
  • 2
  • Cyclic Quadrilateral Theorem: ­ the opposite angles of a cyclic quadrilateral   are supplementary ­ an exterior angle of a cyclic quadrilateral is   equal to the interior opposite angle 3
  • 4
  • 5
  • A convex polygon with n sides can be  divided into (n ­ 2) triangles The sum of the interior angles of a  polygon with n sides = (n ­ 2) x 180 6
  • The exterior angles in an n sided polygon add up to 3600 If there are n sides in a regular polygon then the measure  of each exterior angle in the polynomial will be 3600   n 7

  • Example find the value of each angle 6x +1 6x 1? 2? 2x ­ 2 1400 9
  • Draw a 6 sided regular polygon, determine the measure of  each interior angle Determine the measure of each exterior angle 10
