All three ratios of a side of one triangle to the corresponding side of the other triangle must be the same.
Nothing else, the angle-angle-side is sufficient to show the triangles are congruent. With two corresponding angles are equal, the third angles in the triangles by definition (the sum of the three angles in a triangle is 180o) must be equal making the triangles similar. If a corresponding pair of sides are also equal, then the other two corresponding pairs of sides will be equal.
congruent means that all the sides are the same length. the sides of a square have to be the same length or else it would be a rectangle. Not all triangles are congruent though. there are other types of triangles unlike the square, where there is only one type.
No, else the sides would not be able to close. Triangles may only have one right angle, at any given time. For a triangle to have exactly equal angles; each angle would have to measure sixty degrees - which is known as an equilateral triangle.
A rhombus
The answer depends on what is already known about the two triangles.

Nothing. If a side ,an angle, and a side are the same the triangles are congruent.
Nothing in a scalene triangle is equal to anything else in the same triangle. When you're talking about triangles, 'scalene' means three different angles and three different legs.
Pythagoras theorem is always used in right angle triangles. It can be used to find any of the third side is two sides are given, It can also used to find the area of cone if slant height or anything else is missing.
The 5 are: the tetrahedron, made up of four triangles the hexahedron, made up of 6 squares (this solid is also known as the cube) the octahedron, made up of 8 triangles the dodecahedron, made up of 12 pentagons the icosahedron, made up of 20 triangles at each vertex on these solids, there are an equal number of faces meeting they are all regular polyhedra for each solid, the angles and sides are congruent and if it wasn't obvious already, they were discovered by Plato anything else?

I guess it is a dice or what else is it supposed to be? A hexagon is a plane figure with 6 sides.
Because it has to or else it wouldn't be a triangle, just a random polygon, or other geometric shape.
