If the coordinates of a triangle are (-2,-2) (-1,1) (1,-1) what would be the coordinates if I rotated the triangle 180 degrees c

EleoNora [17]

Answer:

(2,2), (1,-1) and (-1,1).

Step-by-step explanation:

If a point {say P(h,k)} be rotated by 180° about the origin in counterclockwise then the new point generated P' will have coordinates (-h,-k).

Now, if the coordinates of a triangle are (-2,-2), (-1,1), (1,-1) and rotated 180 degrees counterclockwise about the origin then, the coordinates of the new triangle will be (2,2), (1,-1) and (-1,1). (Answer)

Algebra I

Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-5, -7)

Point (-4, 1)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [SF]: $\displaystyle m=\frac{1+7}{-4+5}$
[Fraction] Add: $\displaystyle m=\frac{8}{1}$
[Fraction] Divide: $\displaystyle m=8$
