If you are allowed to "know" that the sum of the interior angles of a triangle is 180 degrees, then you can construct the diagonal of the four sided figure making two triangles and when you add 180 to 180 you get 360.
triangles always have 180 degrees in total. So the degrees for the final angle would be 180 - 93 - 63.
Because there are 540 interior degrees in a five sided figure and the total sum of three triangles is 540 degrees
540 degrees. you figure it out by seeing how many triangles you can make in the polygon (without crossing lines), and, because triangles equal 180 degrees, you multiply 180 times how many triangles you can make.
An obtuse angle.
120 degrees The way to figure any polygon is to draw diagonals from one of the vertexes to all the others and count the triangles. A 6 sided figure has 4 triangles. 4 times 180 = 720 total degrees. Divide that by 6 and you have 120.
ON apex it is 64 degrees......
(20-2)*180 18*180 3240 The way that I remember this is that a triangle, 3 sides, has one triangle in it. A four sided figure, if you draw one diagonal, has 2 triangles in it. So there are 2 less triangles in a figure than the number of sides. A triangle's interior angle measure is 180 degrees.
The simplest pattern is 2n+1, so the 16th figure will have 33 triangles. Of course, if you are creating new triangles and also keeping the old triangles, this would be different.
270 degrees
A straight angle
1080 degrees
90 degrees
