Create and embed and applet that uses the SEQUENCE[] Command in a creative way. You have a lot of freedom, here. However, you need to make explicit how you used the SEQUENCE[] command to do the dirty work. You will need to use the GeoGebra HELP menu to find out how to use it.

GEOGEBRA ASSIGNMENT Due FRIDAY 11/5! Create and embed an applet on your wiki page that shows how the Altitudes, Perpendicular Bisectors, and Medians work. You should include a check box to hide and reveal things, as well appropriate 'DECORATIONS" to illustrate the correct markings on your triangle.You should also include some text to describe any significant features of the special segments.

I simply chose two points that fit the criteria of the problem, and then drew two congruent right triangles.

line RQ ---->
eq=y=-3/4
eq=y=-3/4


line QP ---->
eq=y=4/3
eq=y=4/3


since (4/3)(-3/4)=-1, the slopes are negative reciprocals of each other meaning that the segments are perpendicular. Therefore, angle PQR is a right angle.
