Triangle xyz has vertices x(1, 3), y(0, 0), and z(–1, 2). the image of triangle xyz after a rotation has vertices
x'(–3, 1), y'(0, 0), and z'(–2, –1). which rule describes the transformation?
r0, 90°

r0, 180°

r0, 270°

r0, 360°

The correct answer is:

R0, 90°

Explanation:

When no direction of rotation is listed, we assume that positive angles of rotation indicate counterclockwise movement and negative angles indicate clockwise movement.

From the pre-image points to the image points, the values of x and y have been switched and the value of y has been negated.  Algebraically,

(x, y) → (-y, x).

This is the rule for a 90° counterclockwise rotation through the origin, or R0, 90°.

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
