180 degrees.
Yes, all triangles have the sum of their angles as 180 degrees.
The sum of the internal angles always equals 180o
the sum of the angle sin one triangle is 180, so the sum in three triangles would be 180x3, which is 540 degrees. Hope i helped XD
180
In general, you divide up the polygon into triangles, calculate the areas of the triangles and then sum these.
The sum of the 3 angles of a triangle will ALWAYS equal 180 degrees.
There are 180 degrees in any and all triangles.
180 degrees. Hope I helped :)
The sum of the angles in any triangle is 180. This includes Equalateral triangles.
It can be proven that the angle sum of a triangle is 180 degrees using Euclid's parallel postulate. Any quadrilateral can be divided into two triangles by connecting two opposite sides. The sum of the angles of the quadrilateral will be the sum of the sum of the two triangles, or in other words 2*180=360. In fact, any n-gon can be divided into n-2 triangles and the sum of the angles of the n-gon will be (n-2)*180.
Divide the polygon into triangles. Calculate the areas of the triangles and then sum these.
Yes - in the case of triangles in Euclidian geometry. That is, basically triangles in a plane.
