The way to find the missing side of a triangle-THIS ONLY WORKS ON RIGHT ANGLED TRIANGLES-is square both sides seperately and then add them together to give you the square of the missing side-find the square root and that is the size of the missing side-eg. if you have a RIGHT ANGLED TRIANGLE with sides of 3inch and 4inch then (3x3) + (4x4) = 25 so the square root of 25 is 5 meaning the missing side is 5inch.
Form an equation and solve it

Congruent shapes simply means both shape are identical, therefore to find two right-angled triangles are congruent you:Use a tracing paper and trace the right-angled triangle (A) and see if it matches with the other right-angled triangle (B).Another way is to find the positions or measure the triangles, if the match then viola! they're the same.
With right triangles. To find side length of a, b and c.a2 + b2 = c2=========
The answer depends on what solving is required: do you need to find the area, perimeter, angles, trigonometric rations?

you can't, because the Pythagorean theorem is for right triangles and the triangles formed by the diagonal of a parallelogram are not right triangles.

Trigonometry is used to find the properties of triangles and Pythagoras' theorem is used to find the lengths and angles of right angle triangles.

If you know the hypotenuse and the base then use Pythagoras' theorem to find the altitude
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 idea is that you model a situation with similar triangles and then use proportions to find the missing measurement indirectly.
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
