in trig a reference angle is ised to create a reference triangle in the first quadrant by using any point except the origin that lies on the terminal side of the ref. angle and drawing a perpendicular to the x-axis. for 90 degrees the terminal side is the y-axis and the perpendicular would not create a triangle, but just retrace the y-axis.

Why is 90 degree not taken as the angle of reference in trigonometry?
The angle of reference is in the first quadrant, and 90 degrees angle is not in the quadrant.
What is the highest whole number in 3 words?
That could be taken too many ways to really answer. Take a look at these: (In increasing order) Nine Hundred-Ninety Ninety Thousand-Ninety Ninety Duodecillion-Ninety (million is 1, billion is 2, dodecillion is 12) Ninety Googolplex-Ninety Ninety Googleplex Cubed. Infinity times infinity. Infinity Cubed Cubed (infinity to the power of three, then that to the power of three again) Infinity to Infinity (as in to the power of)
Why angle is taken as double in mohr's circle?
because this is called science...
How do you construct a 60 degree angle using a compass?
Draw a straight line ab putting the centre of compass at a take an arc which cuts ab at point c (let) from point c cut an arc with the same radius which u had taken while drawing the first this cuts the first arc at poiint d(let) join a-d and produce it in the direction of d angle bad is the required angle
How do you measure the contact angle?
There are many ways to measure a contact angle, but the simplest way is to use a goniometer. The image of the droplet is taken with a high resolution camera; the angle can then be measured using a protractor.
