The exterior angle of a triangle is calculated using the formula d = ∠a + ∠b, where d represents the angle between the two interior angles. The sum of the exterior angles of a triangle is always equal to 360°, with three exterior angles in a triangle.
The exterior angle of a triangle can be calculated using various formulas depending on the given situation. For example, if m∠1 = 40° and m∠2 = 80°, the exterior angle is 35° + b. In a given triangle, the exterior angle is equal to the sum of its remote interior angles.
To find the missing interior or exterior angles in a triangle, apply the exterior angle theorem. For example, if m∠1 = 40° and m∠2 = 80°, the exterior angle is 35° + b. The exterior angle is the angle between any side of a shape and a line extended from the next side.
In a regular polygon with N sides, the measure of an exterior angle is equal to 360^o/N. For a general polygon (exterior), the measure is equal to 360^o/N.
In summary, the exterior angle of a triangle is determined by calculating the sum of the measures of the two non-adjacent interior angles. The formula for finding the exterior angle of a regular polygon is 540/5, which gives 108 for each interior angle. For a general polygon (exterior), the measure is 360^o/N.
