Question

A triangle is supposed to have the following characteristics: two sides have length 2 cms, and one of the angles is of size 60° . Does this information result in one triangle, two triangles, more than two triangles, or no triangle at all?

one triangle
two triangles
more than two triangles
no triangle at all

Answer 1

why not draw a couple of triangles that satisfy these specifications (two sides both have length 2 centimeters, and one angle measures 60 degrees)?

Think: Do any of the following sound appropriate or inappropriate: "isosceles," "equilateral," "acute," "obtuse?"

Answer 2

How would you characterize an "equilateral triangle?" an "acute triangle?"
