Triangle ABC has vertices located at A( 0, 2), B (2, 5), and C (−1, 7).

Part A: Find the length of each side of the triangle. Show your work. (4 points)

Part B: Find the slope of each side of the triangle. Show your work. (3 points)

Part C: Classify the triangle. Explain your reasoning. (3 points)\

Thanks!

Perimeter of the triangle = 12 units.

Step-by-step explanation:

Step 1:

Construct a triangle ABC with the given vertices:

refers to the distance between the two points A and B

.

To find the magnitudes of the sides AB, BC and AC, use the distance formula:

Step 7:

Measure the distances between points on the coordinate plane:

Step 8:

Useful information

Measure the angle
