No. If you only know angles, you can't find any sides.
Millions of triangles can all have the same angles. In fact, an infinite number of them can.
No. Given a triangle with only the right angle and the hypotenuse, you cannot calculate the other sides nor the other angles.
A triangle cannot have four angles.
a triangle..
It may have no right angles, and certainly no parallel sides.
An isosceles triangle.
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
Yes. A scalene triangle is, by definition, a triangle with all sides and angles different. An equilateral triangle has all sides and angles the same, an isosceles triangle has 2 sides and 2 angles equal, and a right triangle has a right angle, but it is also possible for an isosceles triangle to be a right triangle.

There are four types of triangles. For an "equilateral triangle", all sides and angles have to be the same. For an "isosceles triangle", 2 of 3 sides and angles have to be the same. For a "scalene triangle", the "the same" rules don't apply. For a "right-angled triangle", one corner has to be a right angle (90 degrees.) For example in an equilateral triangle, as long as the sides are the same, they can add up to anything. However, angles are different. In any given triangle, the angles must add up to 180 degrees.
Two sides, or two angles + one side.
There can be no such triangle.
An isosceles triangle.
Any triangle that is not a right angle triangle
a 'SCALENE' triangle. ; No equal sides, and no equal angles. An ISOSCELES triangle has two equal sides and two equal angles. An EQUILATERAL tringle has three equal sides and three equal angles all at 60 degrees. A RIGHT ANGLED triangle has one right angle (90 degrees) in it.
