ok, I'm really confused with this Question: "Whats the slope of a 0 degree angle, and if so how did u do it or how can u prove it. I need a reply because it is urgent. thx for replying[:)]
Uh, what's the slope of any angle?
A line has a slope. An angle doesn't. You'll have to get the question straight before you have any hope of answering it.

That sounds like nonsense to me. The slope of an angle?

i meant when u graph the angle in a coordianate plane the angle has a rise and run so there should be a slope

If You plot the graph with certain coordinates then
slope \tan\Theta=\frac{\Delta(y)}{\Delta(x)}

Ah a line which makes an angle A with a horizontal line has slope tanA.

what do u mean tanA, Im asking for ppl to show me how to get the slope of a 0 degree angle, and u could graph an angle in a coordianate plane so there must be a run and rise, u could get the slope......................... I do think there's a solution [8)]

What is A for Zero degree, it is zero so u know calculate this prob.

huh?

If you're talking about a line that makes an angle
\theta = 0 ~degrees with the x-axis, the
slope = \frac{\Delta y}{\Delta x} = tan~\theta = 0
To put it in your terms, the rise is 0, so the slope is 0.
But remember, that is the slope of the line, not the angle.

ok......... That answer part of my question but I still think something is missing[?]

i wonder what after the reply of gnome is missing

Did you ever actually draw such a line??
A line with 0 angle is horizontal. All points that it passes through will have the same y component. What do you think the "rise" is??

ok I go the answer and gnome was right, thx[;)]

Since you have the answer now:
In general the slope of any straight line making angle θ with the x-axis is tan(θ). Of course, tan(0)= 0.
