Why Triangle Is 180 Degree? [Solved]
The angles of triangle always add up to 1800 degrees because one exterior angle of the triangle is equal to the sum of the other two angles in the triangle. When all the angles are added up, the sum obtained should be 180 degrees.
Why does the interior angle measures of a triangle equal 180 degrees?
The interior angle measure of all
