Pleaaase ! graph the image of the given triangle, rotated 90 degrees counterclockwise about the origin.

under a counterclockwise rotation of 90° about the origin

a point (x , y)  → (- y, x)

the vertices of the triangle are (2 , 2), (7 , 1) and (8, - 4)

thus (2, 2) → ( - 2, 2)

(7, 1) → (- 1, 7)

(8, - 4) → (4, - 8)

Plot these points, connect them and you have the image.

answer: true

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
