In a right angle triangle the square of the hypotenuse is equal to height squared plus base squared

Do you mean you know the lengths of the sides but you don't know the size of any of the angles ? If that's the situation, then yes. The lengths of the sides tell you everything about the triangle, and they define one and only one unique triangle. With a little bit of trig, you can figure out what the size of each angle has to be.

We at WikiAnswers can't see Bonita's triangle. You'd have to tell us more about the triangle in order to be able to answer this. Please note that WikiAnswers is not here to do your homework for you. If this question is from work you have been assigned by a teacher or professor, I suggest you do the work yourself instead, which will help to increase your understanding of the subject matter and help you to become more familiar with it.

You cannot. If a number is even - other than 2 - then it is a composite number. However, if it is odd, it is not easily possible to tell whether it is prime or composite.

You can't. The hypotenuse alone isn't enough to tell you anything about the triangle. There are an infinite number of different right triangles that all have the same hypotenuse. In order to find anything else, you also need to know either the length of one leg, or else the size of one acute angle.

Same length, same width, same size, same shape

If your asking what shape has three lines of symmetry, your answer would be an equilateral triangle. You can tell how many lines of symmetry a shape that has all angles of the same measure has by looking at it's angles. Ex., pentagon has five angles--five lines of symmetry; octagon has eight angles, eight lines of symmetry; etc.

All triangles are unique compared to other polygons inasmuch that they have only 3 sides and no diagonals.

symmetry principles always tell us something important. They often provide the most valuable clues toward deciphering the underlying principles of the cosmos, whatever those may be. In this sense, therefore, symmetry is certainly fruitful. Whether or not some all-encompassing symmetry is the grand principle that will necessitate our "theory-of-everything" is still to be determined.
