Web6 years ago. So if we know that a pentagon adds up to 540 degrees, we can figure out how many degrees any sided polygon adds up to. Hexagon has 6, so we take 540+180=720. A heptagon has 7 sides, so we take the hexagon's sum of interior angles and add 180 to it getting us, 720+180=900 degrees. Same thing for an octagon, we take the 900 from ... Web1. Introduction. Do the angles of a triangle add up to 180 degrees or radians? The answer is 'sometimes yes, sometimes no'. Is this an important question? Yes, because it leads to an understanding that there are …

WebJan 13, 2010 · A triangle with 3 different sides and 3 different acute angles that add up to 180 degrees is a scalene triangle. What does an equilateral triangle and scalene triangle have in common? Both triangles have 3 sides which add up to 180 degrees. WebSo if this is 40 and that is 50, these two add up to 90. So to add up to 180 degrees, this one must be a 90-degree angle. We can even mark it as a right angle. So if you have a triangle where all of the interior angles are different, that means that all … chris chrisman obituary

WebSee also: Triangle § Non-planar triangles. For a spherical triangle, the sum of the angles is greater than 180° and can be up to 540°. Specifically, the sum of the angles is. 180° × (1 + 4 f ), where f is the fraction of the sphere's area which is enclosed by the triangle. Note that spherical geometry does not satisfy several of Euclid's ... WebA triangle has three sides and three angles : The three angles always add to 180° 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 … genshin ipact notizbuh henry morton
