They use a concrete saw, a gas powered saw, such as Stihl 14", Echo, Wacker.

A right angle is 90 degrees. That's like cutting straight across. A 45 degree angle is exactly half of that. Cut on the diagonal.
Its a right-angle triangle
Yes, because a circle is 360 degrees right?,so when the perpendicular lines meet they cut the circle in half so 360 degrees divided by 4 equals 90 degrees...
HOW TO MAKE 40 DEGREE ANGLE USING RULER AND COMPASSStep 1:-Draw a line segment BC of any measurement.Step 2:-Now, B as center and any radius draw an arc give it as arc (RS).Step 3:-Where the arc rs cut the line segment BC give that point as P.Now, with P as center and same radius cut another arc which intersect the arc RS at point X.Step 4:-With X as center and same radius cut another arc which intersect the arc RS at point Y.Step 5:-with X as center and any radius cut an arc and now,Y as center and same radius cut another arc which intersect the first arc.Step 6:-Now taking Z as center and radius ZP cut another arc.Now taking P as center and same radius cut another arc which intersect the first arc at point Q.Step 7:-Join BQ.At last we get angle QBC=40 degree._BY:-SHIVAM_PALAN"> BY:-SHIVAM PALANP.NO. +91 9371885859ADD.RING ROAD NEARSHIVAM GIRL'S HOSTELGONDIA-441601(MAHARASHTRA)
You need to take what degreee turn you want divide that by how many welds you want that will give you the angle of miter cuts to find your starting piece a take the radius of bend muliply by tangent of miter cut
