90 - 72 = 18 degrees.
If you have one angle, you can draw two line segments that meet at that angle. Then, rotate your paper 180 degrees, and repeat, ensuring that the new lines are parallel to the existing ones, and eventually intersect them. You now have a parallelogram.
A regular 18 sided polygon has 18 exterior angles each measuring 20 degrees
Angles only go up to 360 degrees unless it's 1 and 1/36 of a revolution
Providing that it is a regular polygon then each interior angle will measure 160 degrees
draw the outside angle if you want to show 270 degrees then you draw a 90 degree angle but draw the circle outside of it
A right angle measures 90 degrees
to construct an angle of 20 degrees all you have to do is to trisect an angle of 60degrees
Interior angle is 180 -18 = 162 degrees because there are 180 degrees on a straight line
It will be a right angled triangle with angles of 90, 72 and 18 degrees.
use a protractor
72 degrees.The complement is 18 degrees.72 + 18 = 9072 - 18 = 54
A reflex angle is an angle greater than 180 degrees and less than 360 degrees. To construct one draw two lines at an angle and draw the angle measurement circle around the side you normally don't do it on.
The complementary angle of 72 degrees is 18 degrees
draw 2 angles that add up to 180 degrees
An angle of 180 degrees is a straight line
obtuse* angles are between 180 degrees and 90 degrees. Straight line and right angle.
