Subject:   Isosceles?
Author: Oscar@MU

I think that the sketch included in the Types of Triangles problem of the week
has a problem. The red triangle seems to be isosceles, and it is, but students
would disagree when they see the measures of the lengths of the sides. The
lengths that should appear equal seem not to be, although they are close. The
reason is that the display for one of the lengths was set to units, and the
other to hundredths, hence making the numbers, as displayed, different. This
create an interesting situation, in which a triangle has congruent angles, and
yet the sides aopposite to these angles are not congruent!
