What is the classical problem of angle trisection?
Now on the wikipedia page it says the following, and I quote: "Angle trisection is a classical problem of compass and straightedge constructions of ancient Greek mathematics. It concerns construction of an angle equal to one third of a given arbitrary angle, using only two tools: an unmarked straightedge and a compass.See all results for this questionVideos of Constructing Angles Video Angles Khan Academy B Watch video on Khan Academy2:41Constructing anglesMar 3, 2017Khan Academy Sal KhanSee more videos of Constructing Angles Video Angles Khan Academy BevelingOnMedia Spot  Khan Academy VideosKhan Academy; All.

How do you get a 90 degree angle?
So you could use a 90 degree angle and a 15 degree angle, so the 3rd angle would be 75 degrees. To get the 90, use a right triangle, and to get the 15, use an equilateral triangle, bisect the 60 degree in half, and then the 30 degree in half to get the 15 degree angle.See all results for this questionHow did Pierre Wantzel solve the angle problem?It concerns construction of an angle equal to one third of a given arbitrary angle, using only two tools: an unmarked straightedge and a compass. The problem as stated is impossible to solve for arbitrary angles, as proved by Pierre Wantzel in 1837.See all results for this questionGeometric constructions: congruent angles (video)  Khan constructing angles video angles khan academy BevelingWe can construct congruent angles with a compass and straight edge.
