An acute triangle.
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.
90 - 72 = 18 degrees.
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
In a triangle the measure of the first angle is four times the measure of the second angle. The measure of the third angle is 18 degrees more than the second angle. What is the measure of the first angle? 68 43 17 95
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
use a protractor
It will be a right angled triangle with angles of 90, 72 and 18 degrees.
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 complement of an angle is equal to 90 degrees minus the measure of the angle. Therefore, the complement of a 72 degree angle would be 90 degrees - 72 degrees, which equals 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.
