Sum of angles = (n - 2)*180
This is because from any vertex, you can draw diagonals to the other vertices, which will form (n - 2) triangles. Each triangle has 180 degrees, so the total is (n - 2)*180.
You can also show a pattern
Triangle = 1*180 = 180
Qaudrilateral = 2*180 = 360
Pentagon = 3*180 = 540
Hexagon = 4*180 = 720
Heptagon = 5*180 = 900
Octagon = 6*180 = 1080
etc.
Because of this, the formula for a single angle is
[ (n - 2)*180 ] / n
This is just the total of all the interior angles, divided by the number of angles (which is the same as the number of sides).

the rule to discover the sum of inner angles is n - 2 x a hundred and eighty. enable n characterize the type sides. when you consider which you have been given the consequence, merely artwork backwards, like in case you're fixing an trouble-free linear equation. Divide by employing a hundred and eighty and upload 2, which aspects 24 sides. additionally, the form is noted as a icosikaitetragon. that's an trouble-free question, and you in all possibility could have solved it on your guy or woman.
