1. Draw a circle on a piece of paper.
2. Draw a straight line from the top center line of the circle to the bottom center line.
3. Draw a straight line from the left center line of the circle to the right center line.
These lines should form a plus sign (+). Place your pencil point in the center of the circle where the two straight lines meet. Your pencil point is at the corner of four equal 90 degree angles.
You can follow this method but it is inaccurate. A better way to construct a right angle is as follows:
- Draw a straight line using a ruler
- Use a pair of compasses to mark two arcs on the line that you have drawn
- Place the compass point at the first point and adjust the compass so that the pencil goes just pass the point that you drew the first to lines
- Draw a major arc across the line with the line roughly in the centre
- Repeat for the second point, keeping the compass points the same distance apart
- Join the two points where the arcs meet
You have bisected the line at the first point that you placed your compasses and have created four right angles.

Is 120 degrees an acute or right or obtuse angle?
Obtuse. An acute angle is less than 90 degrees, a right angle is 90 degrees, and an obtuse angle is more than 90 degrees.
How many degrees in a right angle?
There are 90o in a right angle. A right angle is one-quarter of a full circle i.e. 360o.
How do you draw 45 degree angle using ruler and compass?
Construct 2 perpendicular lines which will meet at 90 degrees then by bisecting this angle wll give a 45 degree angle
What angle with a measure of 90 degrees is called a?
An angle of 90 degrees is called a right angle.

How can you construct 135 degree angle only with a scale and compasses?
Construct a perpendicular line that intersects a horizontal line at 90 degrees and then bisect the vertical line with the horizontal line will give an obtuse angle of 135 degrees because 90 degrees+45 degrees = 135 degrees
