For example, you can measure equally each side of a triangle and then also the longer hypotenuse line that joins the 2 other lines together and then from that, work out all the internal angles. If the bevel finder still fits the angle divider exactly, I know all is good. Using a ruler or tape measure, measure the vertical distance between the 2-inch mark on the square and the top of the sill. For example, the angle made by a run of 8 feet and a rise of 12 feet makes the same angle as a run of 8 inches and 12 inches. Given angle and one leg; Find the missing leg using trigonometric functions: a = b * tan(α) b = a * tan(β) Given area and one leg; As we remember from basic triangle area formula, we can calculate the area by multiplying triangle height and base and dividing the result by two. Place the larger rectangular shaped arm of the angle finder flat on the floor. 3 different shape walls and what angle each mitre needs to be cut at for a perfect joint. With our angle set, the next job is to actually measure it to find our angle. Notice when the value is hidden the angle value next to the angle arc is replaced by the corresponding letter. Firstly, place the protractor so that its centre point is directly over the mark we made above that depicts the start of our angled cut. Find the angle on the table below, which includes the most common sill angles. Place a square against the outside stop, or the sash's stile, as shown.
