There are websites with online protractors.
Notice that it has two 80s on it. To form an 80° angle, extend the line through one of the number 80s (it doesn't matter which) down to the crosshairs in the center of the bottom, then draw a line from the crosshairs to the 0 (zero) on the same side as the 80 you started with. Traditionally, angles are drawn facing the right, but if yours faces the left, that's not wrong.
Right angles are ninety degrees. Squash one of those a little bit.
The compliment of a 100 degree angle is a 80 degree angle.
An 80 degree angle is an acute angle because it is greater than 0 but less than 90 degrees.
An acute angle of 80 degrees can be constructed by means of a protractor and a straight edge
It is an isosceles triangle because the third angle must measure 50 degrees
Any angle less than 90 degrees is called actue
10 degrees less than a right angle
a 90 degree angle is a perfect angle of a square so 80 degrees will be 10 degrees less.
It is 10o less than a 90o angle. It has a very steep slope.
The supplement of an 80 degree angle is an 100 degree angle.
180-100=80 degree angle
a 10-degree angle
The compliment of a 100 degree angle is a 80 degree angle.
complementary angles are defined as 90 degrees - the given angle so 90-80=10 10 degree angle is complementary to an 80 degree angle
An 80 degree angle is an acute angle. Any angle measurement that falls below 90 is acute while anything above is obtuse.
100
An acute angle
An 80 degree angle is an acute angle because it is greater than 0 but less than 90 degrees.
