Algebraically prove that a clockwise and counterclockwise rotation of 180° about the origin for triangle abc are equivalent rotations.

Consider the equation 0.2(x – 4.5) + 1.7 = 9.6. 1. use the distribution property. 2. combine like terms. 3. use the properties of equality and inverse operations to isolate the variable. 0.2x + (-0.9) + 1.7 = 9.6 0.2x + 0.8 = 9.6
