standard_description: Apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3 (2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y.
problem_activity: Identify the strategy that the student below used to find the measure of
$${BA}$$
. Then, describe a different method for finding this value, describing how you know that the two triangles are dilations of one another.
