Question
Tricky Triangles
The triangle congruence postulates can be used to determine if two
triangles are congruent. But they can also be used to determine if a set
of measures determines only one triangle. For example, if you're given
three sides of a triangle, does that determine only one possible triangle?
It does, because any other triangle with the same three sides would be a
congruent triangle.
Mr. Arnold Buford makes up a set of problems specifying triangles for
his students to draw. To give his students something to argue about, he
includes some instructions that won't work.
