PLEASE HELP ME Triangle has vertices located at A( 0, 2), B( 2, 5), ( 1, -7).
Part A: Find the length of each side of the triangle. Show your work. ( 4 points)
Part B: Find the slope o each side of the triangle. Show your work. ( 3 points)
Part C: Classify the triangle. Explain your reasoning. ( 3 points)

PART A: Use the distance formula

Line AB:

            =

            =

Line BC:

            =

            =

Line CA:

            =

            =

-----------------------------------------------------

PART B: Solve the slope

Line AB: =

Line BC: =

Line CA: =

------------------------------------------------------

PART C: The classification of triangle

It is scalene triangle. According to PART A, none of the sides are equal, so it is scalene.
