In a geometric shape (say a triangle), the interior angles are those measured on the inside of the shape. The exterior angle is the angle if you were to extend one of those lines to the outside of the shape and measure from that line segment to the other intersecting line. Interior + Exterior = 180 degrees

What is the definition of a regular dodecagon?
A 12 sided shape with equal sides and with equal interior and exterior angles
Which is the best definition of an exterior angle of a triangle?
an angle that forms a linear pair with one of the interior angles of the trinagle.(Apex)
What is relationship between exterior angles and opposite interior angles of a triangle?
The exterior angle of a triangle is equal to the sum of the two opposite interior angles. So if a triangle had points A, B and C: The exterior angle at B would equal the sum of interior angles at A and C. Similarly, the exterior angle at C would equal the sum of interior angles at A and B And the the exterior angle at A would equal the sum of interior angles at C and B.
What is the relationship between exterior and opposite interior angles?
In a triangle, each exterior angle is equal to the sum of the two opposite interior angles.
What is the difference between the sum of the exterior angles to the interior angles?
The exterior angles always, in any shape, add up to 360. The interior angles sum depends on the number of sides.
Interior and exterior angles of triangles?

Which regular polygon's interior angles is three times that of its exterior angles?
octagon interior=135 exterior=45
What is relationship between exterior angles and opposite interior angles of a triangle?
The exterior angle of a triangle is equal to the sum of the two opposite interior angles. So if a triangle had points A, B and C: The exterior angle at B would equal the sum of interior angles at A and C. Similarly, the exterior angle at C would equal the sum of interior angles at A and B And the the exterior angle at A would equal the sum of interior angles at C and B.
What are the interior and exterior angles of a heptagon?
The interior angles can have any value in the range (0, 360) except 180 degrees and the same for the exterior angles. The only constraint is that the sum of the exterior angles is 360 degrees.
What is the sum of interior angles and exterior angle of a pentagon?
Interior angles add up to 540 degrees Exterior angles add up to 360 degrees
What are alternate exterior angles?
they are angles that are usually parallel and that crossed the line that are oppsite from each other
Which polygon has the larger exterior angle triangle or heptagon?
Interior Angles of a Triangle: 60 Exterior Angles of a Triangle: 120 Interior Angles of a Heptagon 128 (approx) Exterior Angles of A Heptagon 52 (approx) Answer: Triangle
What is The sum of the exterior angles of a docegon?
I think its this.... Find the interior. Then do 180 - the interior. That is the exterior. * * * * * The correct answer is that the sum of the exterior angles of any polygon is always 360 degrees.
