Same Side Exterior Angles Math Is Fun

Which are alternate exterior angles.

Same side exterior angles math is fun. All angles equal 60 degrees. Area of Irregular Polygons. See Exterior angles of.

If angle 1 is 123 degrees then angle. Each pair of these angles are outside the parallel lines and on opposite sides of the transversal. Therefore if you have a regular polygon in other words where all the sides are the same length and all the angles are the same each of the exterior angles will have size 360 the number of sides.

Since angles 3 and 4 are supplementary and angles 4 and 5 are the same measure alternate-interior angles are congruent angles 3 and 5 are supplementary. Theorems about Similar Triangles. Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal.

These are a pair of interior angles present on the opposite side of the transversal. According to the theorem they are supplementary meaning that their angles add up to 180 degrees. One angle is interior and the other is exterior.

If the equivalent angle is taken at each vertex the exterior angles always add to 360 In fact this is true for any convex polygon not just triangles. The sum of the exterior angles of any polygon is 360. - corresponding angle are congruent - alternate-exterior angles are congruent - same-side interior angles will be supplementary.

CONSECUTIVE INTERIOR ANGLES MATH IS FUN. In the figure shown AC is congruent to CE. The angle pairs are Consecutive they follow each other and they are on the Interior of the two crossed lines.
