Find the coordinates of the vertices of the triangle if it’s rotated 270° counterclockwise.
Scilla [17]

If these coordinates are rotated 270° counterclockwise, the resulting coordinates will be;

<em>X' = (3, -1)</em>

<em>Y' = (2, -2)</em>

<em>Z' = (-1, -3)</em>

<h3>Rotation of coordinates</h3>

If the coordinates (x, y) is rotated 270° counterclockwise, the resulting coordinate point will be;

(x, y) - > (y, -x)

From the given triangles, the coordinate points are expressed as

<em>X = (1, 3)</em>

<em>Y = (2, 2)</em>

<em>Z = (3, -1)</em>

If these coordinates are rotated 270° counterclockwise, the resulting coordinates will be;

<em>X' = (3, -1)</em>

<em>Y' = (2, -2)</em>

<em>Z' = (-1, -3)</em>
