A compass point of 202.5 degrees falls between the southwest (225 degrees) and south-southwest (202.5 degrees) directions on a standard 360-degree compass rose. It is closer to the south-southwest direction. In terms of cardinal directions, it would be considered closer to the south direction than the west direction.
To construct a 54-degree angle with a compass, start by drawing a straight line using a ruler. Place the compass on one endpoint of the line and draw an arc that intersects the line. Without changing the compass width, place the compass on the intersection point and draw another arc. Where the two arcs intersect is a point that, when connected to the endpoint of the line, forms a 54-degree angle.
To construct a 125-degree angle using a compass and ruler, start by drawing a straight line and marking a point on it (point A). Using the compass, draw an arc centered at point A that intersects the line. Without changing the compass width, place the compass point on one intersection and draw another arc above the line. Repeat this from the other intersection, creating two arcs that intersect. Finally, use a ruler to draw a line from point A through the intersection of the arcs, forming a 125-degree angle with the original line.
Draw a point, and a long straight line through it. Put the centre of the compass over the point, with north on the compass (or zero degrees) on the line. Then draw a second line out from the point at 80 degrees on the compass. You'll then have a 80 degree angle between the lines. It's usually a trick that teachers decide to do on their pupils. A compass is what you use to find north and a pair of compasses is used to draw circles.

To construct a 25-degree bisection angle with a compass, start by drawing a straight line and marking a point ( A ) on it. Next, construct a 50-degree angle at point ( A ) by using a compass to draw an arc from ( A ) that intersects the line at point ( B ), then use the same arc to find point ( C ) such that ( \angle CAB = 50^\circ ). Finally, bisect ( \angle CAB ) by drawing an arc from points ( B ) and ( C ) that intersects at point ( D ), and draw a line from ( A ) through ( D ). This line creates the desired 25-degree angle with the original line.
To bisect an 85-degree angle, start by drawing the angle with its two rays. Next, place the compass point at the vertex of the angle and draw an arc that intersects both rays. Without changing the compass width, place the compass point at each intersection point and draw two arcs that intersect each other. Finally, draw a line from the vertex through the intersection of the arcs; this line bisects the 85-degree angle into two equal 42.5-degree angles.
To construct a 130-degree angle in a parallelogram using a ruler and compass, start by drawing a baseline segment ( AB ). Next, use a compass to create an arc from point ( A ) that intersects the baseline at point ( C ), ensuring that the angle ( CAB ) measures 130 degrees. Then, draw a line from point ( A ) through point ( C ). Finally, replicate this angle at point ( B ) to complete the parallelogram, ensuring that opposite angles are equal.
By bisecting a 15 degree angle with a straight edge and a compass.
Well, honey, you start by drawing a line with your ruler. Then, you put the point of your compass on one end of the line and draw an arc. Next, you put the point of your compass on where the arc intersects the line and draw another arc. Where those arcs meet is your 32-degree angle. Voila!
First draw a horizontal straight line a b Put compass point on a (open compass approximately half the length of line a b - note: ensure the compass is not altered throughout the following). Draw an arc that cuts line a b at c. Put compass point on c and draw an arc from a to cut the first arc at d. Draw a straight line through a d to form a 60 degree angle. For a 120 degree angle, put compass point on dand draw an arc from a to cut the first arc at e. Draw a straight line from a through e to give a second angle of 60 degrees: 60 + 60 = 120 degrees.
Draw a line segment AB. Put your compass point at B and stretch the compass out until it is at point A. Now draw a circle. Now move the compass point to B, leaving the compass opening the same as before and draw another circle. The circles will intersect in two points. Call them C and D. Draw CD and name its intersection with AB as the point E. angle CEB is a right angle. Now you need to bisect the 90 degree angle you just constructed to get two 45 degree angles. Look in your book as to how to bisect an angle. The angle CAB = 60 degrees. So bisect it to get a 30 degree angle and then bisect it to get a 15 degree angle. You can get a 105 degree angle by adding the 90 degree angle and the 15 degree angle. Similarly, you can get a 75 degree angle by subtracting the 15 degree angle from 90 degrees. Look in your book on how to copy an angle.
