I'm using tkz-euclide to draw figures for my students to fill-out.
I'm trying to reproduce this figure, but I have no idea how to make the arrows pointing to the different elements and the dots for them to write.

Here is a MWE:

documentclass[12pt]{article}

usepackage[utf8]{inputenc}

usepackage[T1]{fontenc}

usepackage{pgf,tikz}

usetikzlibrary{arrows,fit}

usepackage{tkz-euclide}

usetkzobj{all}



begin{document}

begin{tikzpicture}

    tkzActivOff

    tkzDefPoints{0/0/A,4/0/B}

    tkzDrawCircle(A,B)

    tkzDefPoint(70:4){C}

    tkzDefPoint(110:4){E}

    tkzDefPoint(170:4){F}

    tkzDefPoint(250:4){D}

    tkzDrawPoints(A,B,C,D,E,F)

    tkzLabelPoints[left](A,F)

    tkzLabelPoints[above](E,C)

    tkzLabelPoint[right](B){$B$}

    tkzLabelPoint[below](D){$D$}

    tkzDrawSegment[color=blue](C,D)

    tkzDrawSegment[color=orange](A,B)

    tkzDrawSegment[color=green](E,F)

    tkzDrawArc[color=red](A,E)(F)

    tkzActivOn

end{tikzpicture}

end{document}

Since tkz-euclide works inside tikzpicture environment, you can use the normal tikz commands to draw arrows and add additional information. I've added some arrows to your pictures, just copy/paste/modify as needed.

    draw[<-, orange, shorten < = 0.3cm] (2,0) -- (5,3) node[at end, right] {Notation:};

    draw[<-, red, shorten < = 0.3cm] (135:4) -- (135:6) node[at end, left] {Notation:};

end{tikzpicture}
