# Geometry - naming parts

Is there a way to get the overline or over arrows for segment, line, and ray names in a textbox or notes box?

Um. This post was forever ago, but no one ever answered? Were you able to figure it out? I like to randomly read through old posts when I am bored. These are what you were looking for?

\overleftrightarrow{AB}
\overline{AB}
\overrightarrow{AB}

They will look like this:
\overleftrightarrow{AB}
\overline{AB}
\overrightarrow{AB}

Yeah, I ended up figuring it out. I was trying to type the latex directly in the math type box. It didnâ€™t occur to me that I had need to type the latex first, then highlight it, and click math type.

Thanks for the help though

I didnâ€™t really follow that because I donâ€™t do it that way, so I donâ€™t know what you mean by clicking math type? I used  marks and $$symbols around the latex. I wonder if someone on here might explain whatâ€™s actually going on. I have been learning everything by copying code. normal pi marks pi$$ symbols
pi

Hm. I expected the  around pi to it into the pi symbol because it was how I turned
\overrightarrow{AB} into \overrightarrow{AB}.

Is this just how people italicize and bold? Is there a list?

I was typing in the notes boxes, and pressing  to start writing equations.
When I do this, I can type notation like x^2 and sqrt, and it will automatically convert it. But typing latex symbols like \overarc{AB} do not convert automatically. I have to type the latex, and then highlight it, and click on a radical button under the box. Clicking this button serves the same purpose as typing `, but only clicking the radical button after typing the latex works.

For symbols like pi, you have to type \ first: \pi

Just a note for others, when typing latex into the Math Type box, itâ€™s turning this:
\overarc{AB}

Into this:
\backslash overarc\left{AB\right}
