It is: 180-exterior angle = interior angle
An interior angle is any angle on the interior of the triangle.
GEF is the alternate interior angle of angle hge.
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
the interior angle is about 128.571428 the exterior angle is about 51.4285
An allied angle is an angle that is found on an interior line. An interior angle is the angle where to lines come together.
Exterior angle + interior angle = 180 Hence Interior Angle = 180 - Exterior Angle The Exterior Angle = n(No. of sides ) / 360 Substituting Interior Angle = 180 - (n/360) Interior Angle = 180 - (18/360) Interior Angle = 180 - (1/20) Interior Angle = 179.95 degrees.
No. It forms the angle and so is neither in the interior nor the exterior.
With a protractor or if you know the exterior angle then it's 180 - exterior angle = interior angle
An interior angle is the inside angle of a shape e.g quadrilateral, square
360
Each interior angle measures 144 degrees
