angles of a square : All four angles of a square are equal. (Each is 360/4 = 90 degrees, so every angle of a square is a right angle.) The diagonals of a square are equal. ..... More from Wikipedia

angles of a square : The hypotenuse of a right triangle is the triangle's longest side; the side opposite the right angle. See also: Computers & Math The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypothenuse equals the sum of the squares of the lengths of the two other sides..

Question : I'm trying to find angles for cutting valley roof rafters using a speed square. I have the directions for using the square, but have one question regarding them and this instruction: "rotate the square around the point until the edge of the board aligns with the correct mark on the "Common" scale...." How do I know what the "correct mark" on the common scale is? What does this mark correspond to?
Answer : To cut hip or valley rafters, you use the Hip-Val scale. Line up with the mark that corresponds to the roof pitch. If you have a 6/12 roof, use 6 on the H-V scale. Another option is to use a framing square, but use 17 instead of 12 for your run. For the jacks, you need a compound cut. Use the common for your miter, and use 45 degrees for your bevel. Remember that the valley rafter must be raised slightly to plane in with the rest of the rafters. Hope this helps... More from Yahoo Answers

Question : I have a homework question where I have to find out if a square's ( plotted on a graph ) corners are right angles. I'm stumped as to how I can get this. I know I can use the pythagorean theorm but I'm pretty sure I'd have to divide the square into triangles wouldn't I ?
any help would be great thanks :) Since some people are confused, I scanned the question and my answer so far.
Hope this helps. And thanks a lot for the answers!!

Answer : Find the slope of the sides of the corner of interest. If they are negative reciprocals of each other, then they are perpendicular. For example, a line with a slope of -3 is perpendicular to a line of slope 1/3. Note: This even works for squares that have sides parallel to the axis if you take the reciprocal of 0 to be infinite. ADDITIONAL RE YOUR WEBPOST: Notice that in your problem (in which you already determined the slopes of the segments) that the slopes are 1 and -1, which are negative reciprocals of each other. Clear?
