WebDec 11, 2024 · This works out perfectly: The measure of each internal angle of an equilateral triangle is 60 degrees, and 6 × 60 = 360, which is exactly what we need around a single point. Similarly for squares: Four squares around a single point at 90 degrees each gives us 4 × 90 = 360. But starting with pentagons, we run into problems. summit windmill golf club \u0026 residence

WebMar 7, 2011 · Copy. Well. Let's say you have a horizontal line (straight from one side to the other). If you had a 90 degrees angle it would go straight up, and 180 is straight to the side. Therefore 120 degrees would be something between that, a bit closer to straight up than straight to the side. I also put a link under "Related Links" below this answer. WebAug 30, 2002 · Start by cutting both the ends at the 30 degree nominal cut. Put both cuts together, should create an angle of 60/120 degrees. Now, use both your drafting triangles. Use the 45/45/90 to establish the 90 degree cut and then butt the 30 degree angle against it = 120 degrees. Now proceed as previously. Cheers, eddie WebAll three angles in any triangle always add up to 180 degrees. So if you only have two of the angles with you, just add them together, and then subtract the sum from 180.
