Draw a straight line, and mark a point somewhere near the middle.
Put the compass on top of the drawing so that the compass points NS along the line and the compass needle is pivoted above the marked point.
Read off 92.5 (or 092.5) on the bearings and mark the position.
Join this point to the point on the line.
The trick to this question lies in the difference between a compass and a pair of compasses. The first is a magnetic device that identifies North, and has angles from North (bearings) marked along its edge. The second is a mathematical instrument, in the form of a hinged V with a sharp point on one leg and a writing implement on the other.
Construct 2 perpendicular lines which will meet at 90 degrees then by bisecting this angle wll give a 45 degree angle
You can use a protractor! Draw the baseline and measure the angles and mark them. Then finally join them together!
First draw a circle. Keeping the compass at the same angle; from any point on the circle's edge, draw another arc that intersects the circle's edge and (should) go through the centre as well. Repeat these arcs until you get back to the start. Using a ruler, connect the six intersect points on the edge of the circle and erase the construction lines.
Suppose you need to bisect angle PQR using only a pair of compasses and a straight edge:Draw an arc with the point of the compass at Q so the arc QP at X and QR at Y.Draw an arc with the point of the compass at X so that the arc is between the arms of the angle and extends to more than halfway across.Without changing the compass setting, draw an arc with the point of the compass at Y so that this arc intersects the previous arc at Z.Using the straight edge, draw the line QZ: this is the bisector of angle PQR.
i think you can use a ruler not sure
first draw a ray .
Construct 2 perpendicular lines which will meet at 90 degrees then by bisecting this angle wll give a 45 degree angle
to construct an angle of 20 degrees all you have to do is to trisect an angle of 60degrees
Yes. First draw a perpendicular (90 degrees) and then bisect the angle.

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.

Geometric figures can be drawn using a compass and a straight edge. This is commonly known as ruler and compass construction.
By bisecting an angle of 30 degrees using a compass and a straight edge
In conjunction with a straight edge and a protractor
With the ruler and compass construct a right angle isosceles triangle with a base of 9 cm At 4 cm from the LHS or RHS of the base draw a line that meets the apex of the triangle The angle of this line will be 40 degrees because each 1 cm of base space represents 10 degrees when joined to the apex
