33. Kyle did his assignment, adding the lengths of the sides of triangles to find the perimeters.
Noticing the results for several equilateral triangles, he guesses that the perimeter of every
equilateral triangle is three times the length of a side. ______________________
34. By using the definition of equilateral triangle (a triangle with three congruent sides) and of
perimeter (the sum of the lengths of the sides of a figure), Katie concludes that the perimeter of
every equilateral triangle is three times the length of a side. _________________
