With a protractor, pencil and a straight edge
Use a straight edge and a protractor to construct an acute angle of 65 degrees
Use a protractor or bisect a 45 degree angle with a compass and a straight edge
by 60 degree and 90 degree
With a protractor and a straight edge
By bisecting a 15 degree angle with a straight edge and a compass.
NO!!! It is OBTUSE. Angles between 0 - 90 degrees are ACUTE Angles between 90 - 180 are OBTUSE Angles between 180 - 360 are REFLEX NB Angle 90 degrees is a RIGHT Angle Angle 180 degrees is a STRAIGHT Line. Angle 360 degrees is one rotation about a given point.
With a protractor
Use a straight edge and a protractor to construct an acute angle of 65 degrees
Obtuse.
A 40 degree acute angle can be constructed with a straight edge and a protractor.
Use a protractor.
2nd Quadrant.
Use a protractor or bisect a 45 degree angle with a compass and a straight edge
by 60 degree and 90 degree
If each interior angle is 165 degree then it's a regular polygon with 24 sides
You'll also need a protractor to construct a 220 degree angle which can then be bisected by means of a compass and a straight line to form two 110 degree angles.
use a protractor and a ruler
