The puzzles are classic examples and a certain amount of deductive reasoning is required to solve them. Some of these puzzles are quite challenging, so don't be discouraged if you have trouble finding the solution immediately. Ideally they will make you think a bit and, along the way, provide a bit of entertainment. We know there are 12 one-cent stamps in a dozen, but how many two-cent stamps are in a dozen?

Draw a line \(\ell\) with a point \(P\) not on \(\ell\). Construct the line \(m\) through \(P\) and perpendicular to \(\ell\) and label the point of intersection of \(\ell\) and \(m\) as \(Q .\) The length of \(\overline{P Q}\) is the distance from \(P\) to \(\ell\). Use a ruler to measure \(\overline{P Q}\) and approximate this distance.
Determine if each conclusion follows logically from the premises and state whether the reasoning is inductive or deductive. Premise: If you are going to be an engineer, then you will study mathematics. Premise: If you study mathematics, then you will get a good job. Premise: Roy is going to be an engineer. Conclusion: Roy will get a good job.
