So if I have an s-sided polygon, I can get s minus 2 triangles that perfectly cover that polygon and that don't overlap with each other, which tells us that an s-sided polygon, if it has s minus 2 triangles, that the interior angles in it are going to be s minus 2 times 180 degrees. Sal is saying that to get 2 triangles we need at least four sides of a polygon as a triangle has 3 sides and in the two triangles, 1 side will be common, which will be the extra line we will have to draw(I encourage you to have a look at the figure in the video). So if we know that a pentagon adds up to 540 degrees, we can figure out how many degrees any sided polygon adds up to. Polygon breaks down into poly- (many) -gon (angled) from Greek. 6-1 practice angles of polygons answer key with work area. And then I just have to multiply the number of triangles times 180 degrees to figure out what are the sum of the interior angles of that polygon. So let me draw an irregular pentagon.

Created by Sal Khan. Same thing for an octagon, we take the 900 from before and add another 180, (or another triangle), getting us 1, 080 degrees. So plus six triangles. The first four, sides we're going to get two triangles. So let me write this down. I can get another triangle out of these two sides of the actual hexagon. And we also know that the sum of all of those interior angles are equal to the sum of the interior angles of the polygon as a whole. Of sides) - 2 * 180. that will give you the sum of the interior angles of a polygon(6 votes). So I think you see the general idea here. But what happens when we have polygons with more than three sides? 6-1 practice angles of polygons answer key with work examples. An exterior angle is basically the interior angle subtracted from 360 (The maximum number of degrees an angle can be). So those two sides right over there. And so if the measure this angle is a, measure of this is b, measure of that is c, we know that a plus b plus c is equal to 180 degrees. So one, two, three, four, five, six sides.

Let's do one more particular example. So it'd be 18, 000 degrees for the interior angles of a 102-sided polygon. And I am going to make it irregular just to show that whatever we do here it probably applies to any quadrilateral with four sides. 6-1 practice angles of polygons answer key with work solution. Сomplete the 6 1 word problem for free. Find the sum of the measures of the interior angles of each convex polygon. But when you take the sum of this one and this one, then you're going to get that whole interior angle of the polygon. 300 plus 240 is equal to 540 degrees.

This is one triangle, the other triangle, and the other one. So the remaining sides are going to be s minus 4. And then we have two sides right over there. So maybe we can divide this into two triangles. So out of these two sides I can draw one triangle, just like that. I can get another triangle out of that right over there. So that would be one triangle there. Orient it so that the bottom side is horizontal. Which angle is bigger: angle a of a square or angle z which is the remaining angle of a triangle with two angle measure of 58deg. So the remaining sides I get a triangle each. Plus this whole angle, which is going to be c plus y. And then, no matter how many sides I have left over-- so I've already used four of the sides, but after that, if I have all sorts of craziness here.

There is no doubt that each vertex is 90°, so they add up to 360°. There might be other sides here. So in this case, you have one, two, three triangles. I got a total of eight triangles. Hexagon has 6, so we take 540+180=720. I have these two triangles out of four sides. So I could have all sorts of craziness right over here. So from this point right over here, if we draw a line like this, we've divided it into two triangles. Now remove the bottom side and slide it straight down a little bit. Let me draw it a little bit neater than that.
The whole angle for the quadrilateral. Let's say I have an s-sided polygon, and I want to figure out how many non-overlapping triangles will perfectly cover that polygon. Hope this helps(3 votes). Take a square which is the regular quadrilateral. The way you should do it is to draw as many diagonals as you can from a single vertex, not just draw all diagonals on the figure. Sir, If we divide Polygon into 2 triangles we get 360 Degree but If we divide same Polygon into 4 triangles then we get 720 this is possible? I'm not going to even worry about them right now.
