All triangles have 3 sides and so two triangles would have a total of 6 sides
Equilateral triangles have 3 sides all of the same lengths and the three angles are equal (60°). Isoceles triangles have two sides of equal length with both of those side angles being equal while the other is different. Scalane triangles have all sides of different lengths and different angles. Right angled triangles have one angle of 90° and the other two will total 90°.
All triangles have a total of 180 degrees. In an isosceles triangle the two angles opposite the side of equal length will have equal degrees.
For a Regular Shape (all angles measure the same), you can split it up into triangles to find the total angle measures. For example, in a square, you can only split it in half, making 2 triangles (below). A triangle always measures 180 degrees, so for an octagon you would split it into triangles from one point. If you count the triangles, you will have 8 triangles. Now Multiple 8 by i80, and your sum of angles will be 1080°.If you then divide it by the sum of the angles in a triangle, or 180 degrees, you will find that 1 angle measures 135 degrees. This rule applies to all Regular Polygons. If you still don't get it,try the link below
60 degrees... since triangles have to have 180 degrees in total, and all sides have to be equal.
Any. All triangles have 180 degrees, so two will have 360.

There are 180 degrees in any and all triangles.
There is 8 triangles in the Star of David.
180 degrees
Well, it just so happens that I figured this out for whoever was wondering... When n is even, and n+1 is odd (obviously) Sn+1 = Sn + (n+2)(3n+2)/4 When n is odd, and n+1 is even (obviously) Sn+1 = Sn + (n+1)(3n+5)/4 These formulas are for the total triangles in something that looks like this... /\ /_\ /\ /\ /_\ /_\ /\ /\ /\ /_\ /_\ /_\ This triangle has n=3 and has 13 total triangles. The general formula for total triangles is hard to find. And because this question doesn't ask for the general solution for any n, I won't post it. It is really fun to find though... The solution is shown below... Total Number of triangles = (n*n) + ( (n) * (n-1) * (4n+1) / 2 ) where n = (k+1) /2. K is the number of triangles on the each side. In the above example k is 3. k = 1 -> Total Triangles = 1 k = 2 -> Total Triangles = 4.875 ~ 5 k = 3 -> Total Triangles = 13 k = 4 -> Total Triangles = 26.875 ~ 27 k = 5 -> Total Triangles = 48 k = 6 -> Total Triangles = 77.875 ~ 78 and so on....
Because the total number of degrees in all triangle is equal to 180. Right triangles consist of one right angle(90) and two equal acute angles(45, 45).
