Have you ever been texting a friend about geometry homework or architecture sketches and suddenly saw the word “perpendicular” pop up in a message, and you were like… wait, what does that even mean in text?
I remember the first time it happened to me I was trying to understand a math problem, and my friend casually said, “Draw the line perpendicular to this one,” and I had to pause and Google it. 😅
Quick Answer:
Perpendicular means “at a 90-degree angle to something.” It’s a neutral, factual term mostly used in educational or descriptive contexts.
In texting, it’s friendly and informative, usually when explaining shapes, lines, or directions.
What Does Perpendicular Mean in Text? 🧠
In simple words, perpendicular describes two lines or surfaces that meet or cross each other at a right angle (90°). It’s a term used in math, physics, engineering, and sometimes even casual design conversations.
Example:
A: “Hey, can you check my drawing?”

In short:
Perpendicular = At a 90-degree angle = Lines or surfaces meeting perfectly straight.
