Is 65 an acute angle
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
Use two theory The sum of the angles of a triangle is always 180 and An the base angles of an issceles triange are equal therefore if one angel is 70 then the two combinations of the angles woudl be 70 - 70 - 40 making 40 the smallest angle 70 - 65 - 65 making 65 the smallest angle
A 65 degree angle is acute.
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
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.)
