Question

Calculate the approximate length of each side of ΔABC with coordinates A(1, 1), B(4, 4), and C(5, 1). Then, classify the triangle as scalene, isosceles, or equilateral.

AB ≈ _________


BC ≈ _________


AC ≈ _________


So, ΔABC is __________

Answer 1

Line AB = 4.24

BC = 3.16

AC = 4

So ABC is scalene.

Answer 2

Explanation:

Line AB = sqrt18 = 4.24

Line BC = sqrt10 = 3.16

Line AC = 4

Since the triangle cannot be isosceles or equilateral, the best option here is scalene.
