Proof: Sum of Angles in a Triangle is 180 Degrees | Geometry Proofs, Angles of a Triangle

Описание: Why do triangles have 180 degrees? In Euclidean geometry, such is life, the sum of angles in a triangle is 180 degrees. Pick a triangle, any triangle, and its three angle measure will add up to 180. But why should this be so? Well, in this video I have a great geometry proof for you. We will dive headfirst into the wonderful world of triangles and mathematical proof to show why triangles do indeed have an angle sum of 180 degrees. Strap up, and let's get to mathing!

I hope you find this video helpful, and be sure to ask any questions down in the comments!
