An angle of 65° can not be trisected using a compass and straight edge.
Use a straight edge and a protractor to construct an acute angle of 65 degrees
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.
65 degrees is an acute angle
The complementary angle of 65 degrees is 25 degrees and together they form a right angle of 90 degrees.
An angle of 65° can not be trisected using a compass and straight edge.
A 65 degree angle is acute.
Is 65 an acute angle
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.

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.
