Negate each of the x and y components of all three vertices of the triangle.
For example, a triangle with vertices (1,2), (8,3), and (5,6) would become
(-1,-2), (-8,-3) and (-5,-6) when rotated 180 degrees about the origin.

Correct; sum of angles of a triangle is 180 degrees.
the answer is................. 180 degrees180 :)The 3 angles inside a triangle add up to 180 degrees.
The sum of the three interior angles inside a triangle is always 180 degrees.
There is 180 degrees in every triangle.
All triangles have 180 degrees.
