Triangle DEF has vertices located at D (2, 1), E (3, 5), and F (6, 2). 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)

DE = units, Slope = 4

EF=  units, Slope = -1

DF = units, Slope =

Isosceles acute angled triangle.

Step-by-step explanation:

Given three points:

D (2, 1),

E (3, 5), and

F (6, 2)

To find:

a) Length of each side.

b) Slope of each side.

c) Classification of triangle.

Solution:

Please refer to the attached image for the triangle.

Length can be calculated by using Distance formula:

Formula for slope is given as:

For DE:

For EF:

For DF:

We can see that DE = DF

So, the triangle is Isosceles acute angled.
