yes, or else the formula A=180(n-2) or more specifically A=180(3) wouldn't work
btw, if u havent noticed, my formula is missing something.
if u know what it is, can u edit it for me, because i cant remember
Because there are 540 interior degrees in a five sided figure and the total sum of three triangles is 540 degrees
Yes
Yes
yes
Yes because there are 540 degrees in a pentagon and 180 degrees in a triangle so 540/180 = 3 triangles.
Yes because 3*180 are the interior degrees of a pentagon.
Yes. You can always draw a "diagonal" line between opposite corners of any four-sided figure. Then, cutting along that line, you wind up with two triangles out of which the figure could have been made.
You can always find opposite corners that can be connected with a line which divides the quadrilateral into two trilaterals.
It is a three dimensional figure of some sort.
A 16 sided polygon is made from 14 triangles
A dodecagon is a 12 sided shape made from 10 triangles
Because the sum of the sides of three triangles is nine... Placing three triangles together so they all touch effectively removes four of the total number of sides - leaving five.
