Question

Determine the property, definition, postulate, or theorem that bestjustifies each statement.Given: AC = BD; AB = 3x - 2; CD = 10ABсDIf A, B, C, and D are collinear,then AC = AB + BC and BC +CD = BD

Answer 1

Given that:

AC = AB + BC and BC + CD = CD

The property that describes this will be the substitution property of equality.

Therefore, we have:

AB + BC = BC + CD

ANSWER:

Substitution property
