3 In each case, choose one of the statements
$$\mathbf { P } \Rightarrow \mathbf { Q } \quad \mathbf { P } \Leftarrow \mathbf { Q } \quad \mathbf { P } \Leftrightarrow \mathbf { Q }$$
to describe the complete relationship between P and Q .
- For \(n\) an integer:
P: \(n\) is an even number
Q: \(n\) is a multiple of 4 - For triangle ABC :
P: \(\quad \mathrm { B }\) is a right-angle
Q: \(\quad \mathrm { AB } ^ { 2 } + \mathrm { BC } ^ { 2 } = \mathrm { AC } ^ { 2 }\)
