How to draw a simple triangle?

I want to draw two simple triangles, (equilateral triangles). Then when i will click on one of the triangle and it will save its values in any file e.g Excel sheet. so any one can help it would be pleasure. Thanks in advance.
My Matlab level is moderate. i dont know too much about it.
Note: I know how to save values in excel. but don't know other stuff.

You can use line or plot.
line([x1,x2], [y1, y2], 'Color', 'r');
hold on;
line([x2,x3], [y2, y3], 'Color', 'r');
line([x3,x1], [y3, y1], 'Color', 'r');
% get user input
[x, y] = ginput(1);
if inpolygon(..............
and so on.
Try this:
p = nsidedpoly(3, 'Center', [1 ,1], 'SideLength', 1);
plot(p);

how can I draw a rotated triangle with a certain angle?
If you use the same example must be:
p_rotated=rotate(p,theta,rotation_center)
plot(p_rotated)
