Find the measures of the exterior angles on following polygons.
The sum of the exterior angles of any polygon is 360o
so, since the number of angles will be the same as the
number of sides, then all you have to do is divide 360
by the number of sides.
• triangle 360 / 3 120
• quadrilateral 360 / 4 90
• pentagon 360 / 5 72
• octagon 360 / 8 45
• decagon 360 / 10 36
• triacontagon 360 / 30 12
• pentacontagon 360 / 50 7.2
• hectogon 360 / 100 3.6
