Web26 jan. 2024 · Alternate exterior angles are created when three lines intersect. A line that crosses two or more other lines is called a transversal. Often, two of the lines will be parallel, setting up some interesting angles with the transversal. When a transversal crosses two other lines, it creates an exterior and interior for the parallel lines ...

WebExamples. These lines are parallel, because a pair of Corresponding Angles are equal. These lines are not parallel, because a pair of Consecutive Interior Angles do not add up to 180° (81° + 101° =182°) These lines are parallel, because a pair of Alternate Interior Angles are equal. hot springs near cincinnatiWebAnd so we say that alternate interior angles are equivalent. So you see that they're kind of on the interior of the intersection. They're between the two lines, but they're on all opposite sides of the transversal. Now you don't have to know that fancy word, alternate interior angles, you really just have to deduce what we just saw over here. hot springs near cincinnati ohio

"Web28 mrt. 2024 · Sum of exterior angles = n x 180° – Sum of all interior angles…. (1) Putting the formula for sum of all interior angles in (1) we get, Sum of exterior angles = n x 180° – (n-2) x 180°. = n x 180° – (n x 180° + 2 x 180°) = 180°n – 180°n + 360°. = 360°. Hence, Sum of the exterior angles of any polygon is 360°. " - How to calculate alternate interior angles
