(-1,3) (3,0) (-1.-2) find perimiter

≈

Step-by-step explanation:

Find the distance between the three pairs first using the distance formula:

Take the first two points, and insert the values:

Simplify parentheses (two negatives makes a positive):

The distance between the first two points is 5. Use the nest two points, and insert values:

Simplify parentheses:

The distance between the nest two point is about 4.5. Use the remaining two points, and insert values:

Simplify parentheses (two negatives makes a positive):

The distance between the last points is 5. Add the distances together to find the perimeter of the triangle:

The perimeter is about 14.5.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
