If one of the other angles is x (degrees or radians in any units), then the ratio is sin(x) : cos(x).
It's Sine!
Yes, an isosceles right triangle will have angles 45-45-90 As a side note, the ratio between the hypotenuse and the sides will always be s: s * √2 where "s" is the length of one of the sides of the isosceles right triangle.
No.
That's the cosine of the angle to which the 'adjacent' side is adjacent.
it depends on how long the triangle is
You know a when a triangle is scalene if all its sides are diffrent lenths none of them are the same

It's Sine!
A right-angled triangle can be an Isosceles Triangle, but NOT an equilateral triangle. An Isosceles triangle has two sides of equal length. They form the 90 degree (right angle). The hypotenuse is opposite the right angle, and is longer than the other two sides.
Proportional to the sine of the angles opposite them.
There can be no tangent side. The tangent of an angle, in a right angled triangle, is a ratio of the lengths of two sides.

No.
Lenths of the 2 shortests sides added together has to be greater than length of the longest side.
