what is the correct name..........?

Question

what is the correct name for an up-side down t....is it called a T-sqaure??

Answer 1

do you mean "perpendicular"? That's what an upside down capital T would look like.

Answer 2

No, a t-sqaure is a drafting tool used in architecture.
the upside down T means "is perpendicular to"

Answer 3

In some types of higher math it's used to indicate orthogonality, which is roughly equivalent to perpedicular.

This is especially the case for vector spaces.

It probably means perpendicular for you. Two vectors are perpendicular iff = 0, that is, their innner (or dot) product is zero.

Answer 4

I believe you are describing the symbol for "Perpendicular".

I've heard of the symbol itself being called "up tack", but I never use that name in a sentence.

(Two lines are perpendicular if they meet at right angles, like the edges of a square.)

Answer 5

The symbol for perprendicular looks like an upside down 'T'.

Answer 6

no a T square is a thing used in drafting so when you draw a line, it isnt crooked, it can be used to hook on the end of a desk so you line up the line( as odd as it sounds)

you have your paper, you want to attach it to the desk or whateva so you can draw a straight line on it withought it moving, so you use a T-square to line up the eadge or bottom of the paper to the desk, so your paper isnt slanted when you use a ruller or whateva to draw a line

Answer 7

I don't think it has a name....just say perpendicular to...in a case of line AB (inverted T) CD : AB is perpendicular to CD

Answer 8

What??
