MAFS.8.G.1.1

Verify experimental properties of rotations, reflections and translations:

1. Lines are taken to lines, and line segments to line segments of the same length.
2. Angles are taken to angles of the same measure.
3. Parallel lines are taken to parallel lines.

MAFS.8.G.1.2

Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.

MAFS.8.G.1.3

Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.

MAFS.8.G.1.4

Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.

MAFS.8.F.1.1

Understand that a function is a rule that assigns to each input exactly one output.  The graph of a function is a set of ordered pairs consisting of an input and the corresponding output.

MAFS.8.F.1.2

Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).

MAFS.8.F.2.4

Construct a function to model a linear relationship between two quantities.  Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph.  Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.

MAFS.8.F.2.5

Graph proportional relationships, interpreting the unit rate as the slope of the graph.  Compare two different proportional relationships represented in different ways.

Learning Targets and Learning Criteria

Students are successful when they can…

• explain how transformations can be used to prove that two figures are congruent or similar.
• perform a sequence of transformations to prove or to disprove that two given figures are congruent or similar.
• describe and apply the properties of translations, rotations, and reflections on lines, line segments, angles, parallel lines and geometric figures.
• describe a sequence of rigid motions to map one figure onto another.
• describe the changes occurring to the x- and y-coordinates of a figure after a translation, reflection, rotation, or dilation.
• identify a function from a graph, equation or set of ordered pairs.
• explain that a function represents a relationship between an input and an output depends on the input; therefore, there can only be one output for each input.
