The first steps to constructing a 135-degree angle are constructing a right angle first (90 degrees angle) 1. using your ruler draw a straight line and name the ends O and A right angle is the standard by which all carpenters build. When corners meet at 90 degrees, drawers fit snugly, windows close tight, and walls stand straight. The key to all this is a square. Most provide a fixed 90-degree angle in various forms, and some can help copy or draw other angles  ### Tools to Measure Angles - The Home Depo

Now sometimes on a test you might have a true and false question is it possible to construct a 22.5 degree angle, or your teacher might ask you to do that. Once you've created your 90 degrees angle, if you bisect it once, you get 45 degrees. If you bisect 45 degrees you'd end up with 22.5

VI (Sep-Oct. 2014), PP 52-55 www.iosrjournals.org Angle Trisection by Straightedge and Compass Only Nikolaos Vrettos Greece Abstract: For many centuries since ancient times the angle trisection has remained one of the three geometric problems that could not have a clear solution by straightedge. Construction of 75 degree. Construction of 45 degree angle: Step 1: Draw the line PQ, to be one leg of the angle Step 2: Set the compass on P and the width to just over half PQ. Step 3: From P and Q, draw intersecting arcs above and below PQ. Step 4: Draw a straight line between the two arc intersections To construct 75 degree angle follow these steps: Draw a ray OA. Taking the O as center draw an arc of any radius on the line OA. label the intersecting point as B. Taking B as a centre with the same radius draw an arc to intersect the previous arc at C. Taking C as a centre with the same radius draw an arc to intersect the previous arc at D A 22.5╦Ü angle can be obtained by bisecting a 45╦Ü angle. Example: The figure shows a point A on a straight line. Construct an angle of 45╦Ü at point A. Solution: Construct a 90╦Ü angle, and then construct an angle bisector to obtain a 45╦Ü angle.
