Teeth of man and mandibles of cockroach are homologous/analogous organs.

Explanation

To determine whether the teeth of a man and the mandibles of a cockroach are homologous or analogous organs, we can follow these steps:

### Step 1: Define Homologous and Analogous Organs
- **Homologous organs** are those that have a common evolutionary origin but may serve different functions. For example, the forelimbs of mammals like humans, bats, and whales have similar structures but are adapted for different functions (grasping, flying, swimming).
- **Analogous organs**, on the other hand, have different evolutionary origins but perform similar functions due to adaptation to similar environments. For example, the wings of bats and insects serve the same function (flying) but evolved independently.

### Step 2: Analyze the Origins of the Teeth and Mandibles
- The teeth of a man (human) are derived from the evolutionary lineage of mammals, specifically vertebrates.
