Interior Angles And Exterior Angles Of A Triangle. Lets explore their relationship by first recalling what the sum of all 3 interior angles of a triangle is. The remote interior angles are just the two angles that are inside the triangle and opposite from the exterior angle.
Exterior angle is defined as the angle formed between a side of triangle and an adjacent side extending outward. The remote interior angles are inside the triangle and are the angles far away also known as remote from the exterior angle. Be sure to change the locations of the triangles WHITE VERTICES each time before you drag the slider.
Lets explore their relationship by first recalling what the sum of all 3 interior angles of a triangle is.
Applying the exterior angle theorem add the two opposite interior angles to find the unknown exterior angle of a triangle. Its all about extending a side of the triangle. Applying the exterior angle theorem add the two opposite interior angles to find the unknown exterior angle of a triangle. Move each of the points around to discover what the relationship between these 3 angles is.
