Why is it possible for a triangle to contain a 180 degrees angle?
because 180 degrees is a strait line, thefore unless the triangle does not have any strait lines the triangle has 3 180 degree angles in it.
If two angles in a triangle are 120 degrees what would the third angle be?
The premise is impossible. The sum of the angles of a triangle is 180 degrees.
Why is it impossible for a triangle to contain a 180 degree angle?
By definition, a triangle must have three angles. It is also known that the interior angles of a triangle must total 180 degrees. If a triangle contained a single interior angle of 180 degrees, the other angles of the supposed triangle would both have to be zero, and the supposed triangle would be a straight line.Triangles have 3 angles.All of the interior angles must add up to 180 degreesIf 1 of them was 180 degrees, the other 2 angles would have to equal 0 degrees, in which case, it would just be a line.
Can a triangle have 2 right angles?
No, a triangle has to have a combined sum of the 3 angles at 180 degrees, a right angle is 90 degrees. It is impossible to have a 90,90,0 triangle
What is the sum of the angle measures in a triangle?
The angle sum of a triangle is 180. 180(n mulitiply by 2) 180 mulitiply by n= answer
