--ANGLES IN QUADRILATERALS--
"A quadrilateral is a polygon with 4 sides, 4 vertices (corners), and 4 interior angles, and the most important RULE is that
'All 'interior' angles total 360°'"
"Now complete this worksheet."
-ANGLES IN IRREGULAR/REGULAR POLYGONS--
"An irregular polygon is a shape where the sides and angles are 'NOT ALL' equal." (Note: some can be equal, just not all), whereas "A regular polygon is a shape where all sides and angles are equal."
"INTERIOR Angles of an irregular/regular Polygon"
Rule: 'The sum of all its interior angles is equal to the number of sides (('n') - 2) x 180°.'
"Prove it, baldy!!!" "Ok, shorty, how many triangles do you see in the 6-sided polygon below?" and "How many degrees in a triangle are there?" and "Do you get it now?"
"Check this rule for yourself below!"
"EXTERIOR Angles of an irregular/regular Polygon"
Rule: The sum of all its exterior angles is always = 360°
"Check this rule for yourself below!"
"Now complete these worksheets."
