Algebra II Exercise: Classifying a Triangle Using the Distance Formula

Review Course Notes

Determine if the following are equilateral, isosceles, or scalene triangles using the three corner points A, B, C.

General Questions
 A = (-2, 0)B = (2, 0)C = (0, -3)
 1 equilateralisoscelesscalene

 A = (1, -9) B = (0, -3) C = (-4, -5)
 2 equilateralisosceles scalene

 A = (0,0) B = (6,0) C = (3,)
 3 equilateralisoscelesscalene

 A = (2, 4) B = (5, 7) C = (8, 4)
 4 equilateralisoscelesscalene

 A = (-3, -3) B = (-8, -5) C = (-1, -8)
 5 equilateralisoscelesscalene

 A = (-8, 1) B = (-2, -3) C = (4, -1)
 6 equilateralisoscelesscalene

 A = (2, -2) B = (8, -3) C = (-6, 7)
 7 equilateralisoscelesscalene

 A = (-5, 0) B = (5, 0) C = (0, )
 8 equilateralisoscelesscalene

 A = (, -5) B = (, 3) C = (0, -1)
