Final answer:
Two bends are not normally required to form compound 90° bends in vector analysis; vectors can form right angle triangles and the Pythagorean theorem can be used to find resultant vectors.
Step-by-step explanation:
The two bends are normally used to form the bends for compound 90° bends is False. In the context of physics and vector analysis, the fraction provided doesn't relate directly to compound bending. However, regarding vectors and their components, a single vector can be resolved into two perpendicular components forming the shape of a right angle triangle, as stated in the referenced fact that a vector can form the shape of a right angle triangle with its x and y components (True).
A compound 90° bend is formed by a single bend in the conductor. This bend can be either upward or downward, depending on the direction of the current.Moreover, using the Pythagorean theorem, we can calculate the length of the resultant vector obtained from the addition of two vectors which are at right angles to each other as indicated by the provided information.
