Trig ratios or to give them their proper name are trigonometrical rations applicable to right angle triangles and they are tangent ratio, sine ratio and cosine ratio.
Tangent, in geometry, is used to describe when figures have only one point in common. In Trig. tangent is applied to triangles.
The difference between plane and spherical triangles is that plane triangles are constructed on a plane, and spherical triangles are constructed on the surface of a sphere. Let's take one example and run with it. Picture an equilateral triangle drawn on a plane. It has sides of equal length (naturally), and its interior angles are each 60 degrees (of course), and they sum to 180 degrees (like any and every other triangle). Now, let's take a sphere and construct that equilateral triangle on its surface. Picture an "equator" on a sphere, and cut that ball in half through the middle. Set the top half on a flat surface and cut it into four equal pieces. Now if you "peel up" the surface of one of those quarters and inspect that triangle, it will have three sides of equal length, and will have three right angles. Not possible on a plane, but easy as pie on the surface of a sphere. Spherical trig is the "next step up" from plane trig.
That depends on your profession. If you are a math teacher, then you might use a lot of Trig. If you are an engineer, working with forces on any object from different directions, then you would use trig. Electrical engineers use trig. Surveyors use trig.

Yes, trig is the math of triangles, particularly right trianges.
By themselves, they cannot. Two similar triangles have the same angels and so they have the same trig ratios. You need to know the length of at least one side to determine the area.

Trigonometry is the study of triangles. Since you use triangles in quilting, technically trig is a part of quilt making. No quilt maker I have ever known has used trig (other than myself). Geometry is used more in quilt making than trig.
Tangent, in geometry, is used to describe when figures have only one point in common. In Trig. tangent is applied to triangles.
Yes. Look up the law of sines and the law of cosines as examples. there are also formulas that can find out the area of a non-right triangle.
Trigonometry functions are used to work out the various properties of triangles.
subtract 90 from it and find the trig ratio of that and it will be equal to the trig ratio that is over 90 degrees
Since trig functions are no more than ratios between the sides, it is unitless.
There is no one or two or a few 'fathers of trigonometry.' Ancient Sumarians, Babalonians started using ratios of sides of triangles. The Greeks continued the study, but emphasized geometric methods instead of algebraic methods that used in trig. Egyptians, Persians, Arabic, and Indians all contributed to the development of trig. This whole process took about 2000 years, maybe more.
