Is 65 an acute angle
A 65-degree angle is classified as an acute angle, as it measures less than 90 degrees. It is also known as a "small angle" in trigonometry. In geometry, a 65-degree angle would be considered acute and would fall between 0 and 90 degrees.
By using a protractor and a straight edge
It must be 65 degrees because there are 180 degrees in a triangle. 90+25+65 = 180
It is an acute angle if it measures 65 degrees
Is 65 an acute angle
the completment of a 65 degree angle is 130
Yes. The fourth angle is 115 degrees.
A pair of supplementary angles total 180 degrees. In this instance, the supplement to a 65 degree angle would be 180 - 65 = 115 degrees.
Use a straight edge and a protractor to construct an acute angle of 65 degrees
Cos(65 deg) = 0.4226 approx.
It's hard to explain without visual representation. But imagine a 90 degree right angle. Okay, it makes an L, now image a 90 degree angle a little more acute (smaller than 90) that in sense is a 65 degree angle.
An angle of 65° can not be trisected using a compass and straight edge.
45 degree angle
A 65-degree angle is classified as an acute angle, as it measures less than 90 degrees. It is also known as a "small angle" in trigonometry. In geometry, a 65-degree angle would be considered acute and would fall between 0 and 90 degrees.
By using a protractor and a straight edge
Supplementary angles are angles whose sums =180 degrees. You have a 65 degree angle + it's supplementary angle = 180 degrees. So, to find the supplementary angle, subtract 65 from 180. 180 - 65 = supplementary angle. 115 = supplementary angle. To check, add the angles together. 65 + 115 = 180 (check) (Also, you might be working with complimentary angles. Complimentary angles are angles whose sum = 90 degrees.)
