Frequent Questions – 💬

❓ How do you calculate exterior angles?

  • The measure of each exterior angle is 360°/n
  • Sum of exterior angles of a polygon is ∠a’ + ∠b’ + ∠c’ + ….. + ∠n’ = 360°.
  • The sum of the exterior angles is 360°.

❓ How do you find the measure of an exterior angle?

To determine the measures of the exterior angles, we need the measure of at least one exterior or interior angle. We use the facts that the sum of the exterior angles is equal to 360° and that the sum of an interior angle and its corresponding exterior angle is equal to 180°. Determine the measures of the missing exterior angles.

❓ What are alternate interior and exterior angles?

  • The alternate interior angles are equal in measure.
  • They lie on the alternate sides of the transversal.
  • They lie in between the interior of the two lines.
  • In other words, the angles that lie on the inner side of the parallel lines but on the opposite sides of the transversal.

❓ What is the formula for alternate exterior angles?

∠1, ∠2, ∠7, ∠8 are the alternate exterior angles Alternate Angles Theorem Alternate angle theorem states that when two parallel lines are cut by a transversal, then the resulting alternate interior angles or alternate exterior angles are congruent.

Do interior and exterior angles add to 180?

Each interior angle in a square is equal to 90 degrees. Notice that an interior angle plus the adjacent exterior angle is equal to 180 degrees. Interior angle + adjacent exterior angle = 180 degrees. In fact, the sum of ( the interior angle plus the exterior angle ) of any polygon always add up to 180 degrees.
