It is: 180-interior angle = exterior angle
because INTERIOR ANGLE 180 AND the exterior angle 180 so 180+180=360
Interior angle+exterior angle = 180 degrees
That depends on what type of triangle it is but in general:- 180-interior angle = exterior angle
-- A scalene triangle has three interior angles and three exterior angles. -- The sum of the interior angles is 180 degrees, and no two of them are equal. -- The sum of the exterior angles is also 180 degrees, and no two of them are equal. -- The sum of each interior angle and its adjacent exterior angle is 180 degrees.
It is: 180-interior angle = exterior angle
It is: 180-interior angle = exterior angle
180 minus interior angle = exterior angle
It is: 180-interior angle = exterior angle
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
because INTERIOR ANGLE 180 AND the exterior angle 180 so 180+180=360
180-the interior angle.
Interior angle+exterior angle = 180 degrees
An exterior angle of a triangle can have a value between (but not including) 0 to 180 degrees.
In any triangle exterior angle plus interior angles = 180 degrees
a triangle has 180 degree but each exterior has 90 degree .
No.Take a look at this picture...http://www.onemathematicalcat.org/Math/Geometry_obj/graphics/summing_exterior_angles.pngThe exterior angle + the interior angle = 180 degrees180 - the interior angle = the exterior angle
