Okay, five.
00:02
So the measurement of an integral polygon is 120 degrees.
00:05
How many sides make up a polygon? alright, so here's how you do that.
00:12
Okay, this form, n minus 2 times 1 80 is the formula for if you're given the amount of sides that a shape has and like in being like, i'm sorry, how much of the interior angles inside of a shape.
00:30
So you make n3, that's a triangle.
00:32
3 minus 1 is 180.
00:33
Yeah, there's 1 in the 80.
00:34
Inside a triangle.
00:35
You make quadrilateral.
00:37
That's 4 minus 2.
00:39
That's 360.
00:40
That makes sense.
00:40
Like a rectangle is 360 on the inside.
00:42
So that's kind of true for any shape.
00:44
And we also know that there's 120 degrees.
00:47
Regular polygon means that all the sides are 120.
00:51
So that's 120...
