A triangle has only 1 right angle. It only has one side that can possibly be a right angle. The type of triangle varies.
No. Angles don't have anything called a side length. However, one can use trigonometry to compute the angles of a triangle based on the side lengths of the triangle (triangles do have side lengths).
It is not an axiom, but a theorem.
There are 3 angles in a triangle.
How many sides of each triangle and how many angles of each triangle do you have ? If you have two sides and the angle between them, or two angles and the side between them, equal to the same parts of the other triangle, then your triangles are congruent. You don't even have to know what the actual numbers are. If the expressions are equal, then the sides or angles are equal.
three
A triangle has only 1 right angle. It only has one side that can possibly be a right angle. The type of triangle varies.
Every side of any triangle is a side of each of two angles. In fact, every side of every polygon is a side of each of two angles.

A triangle has 3 angles.
Every triangle has three sides and three angles

If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
Either of the two angles of a triangle that has the base for a side.
False
If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, then the two triangles are congruent.
