Conversation

Have you ever used a goniometer for measuring angles?

No, I haven't, but I've heard they can be really accurate.

Yeah, I found one in the lab, and it seemed pretty interesting.

Sounds cool! I’d love to see how it works.

Root Explanation

Goniometer → It is formed from "gonia" (from Greek 'γωνία', meaning angle) and "metron" (from Greek 'μέτρον', meaning measure). A goniometer is an instrument used to measure angles.

Memory Tip

Think of measuring 'angles' ('gonia') with a 'measuring' tool ('metron') — that's what a goniometer does.
