Geometry Online HW

Hello!

Please do the following:

1.  Go and play around with the applet of the circumcenter:  http://www.analyzemath.com/Geometry/Circumcircle/Circumcircle.html

2.  Go and play around with the applet for the Euler Line:  http://www.mathopenref.com/eulerline.html

3.  Go and play around with the applet for the incenter:  http://www.mrperezonlinemathtutor.com/CARFILES/Incenter_Incircle_Inradius.html

4.  Write up a description with a sketch of all of the different “centers” and bring to class on Monday.

5.  Do a google search and find another applet that you like for any of the centers and post your response here.

6.  Respond to one of your classmates and tell them what you liked or didn’t like about the applet that they posted.

7.  Bring to class more information about the Euler Line.

    this is the applet i found. it’s the same site as the one you gave us w/the euler line, but it’s the only one i could find that would load :/ this link takes you to an applet for JUST the orthocenter

    Hi, this is weird applet that I found on centroids. I can’t decide if the eyes are creepy or cool. http://www.cut-the-knot.org/Curriculum/Geometry/ParaInTriangle.shtml
    P.S. yes acacia you are on the right pages

    this is an applet for the circumcenter http://www.mathopenref.com/trianglecircumcenter.html adn i dont understand how the circumcenter can lie outside the triangle

    • #10 by laura j. on March 6, 2011 - 8:30 pm

      It can lie outside the circle if one the angles measures over 90 degrees.

    justin, what i don’t like about yours is that you don’t see the circle around the triangle, so you can’t see how the three lines intersect in “the circle’s” center.

    http://www.mathopenref.com/trianglecircumcenter.html // i just find same site with acacia////and this site http://www.mathopenref.com/trianglecircumcenter.html //almost same site whatever… they have all points i think lol

    here is a website that shows the orthocenter and the circumcenter

      My number 14 post was a reply to this.

    oh this website is awesome….you can make your own circumcenter, orthocenter and centriod plus more…oh mine wins.

    It was okay, only the third screen was sort of confusing with the three circles. I had a hard time understanding what it was showing.
