Two-dimensional shapes. The student applies mathematical process standards to develop transformational geometry concepts. The student is expected to:

 

(A) generalize the properties of orientation and congruence of rotations, reflections, translations, and dilations of two-dimensional shapes on a coordinate plane;

 

(B) differentiate between transformations that preserve congruence and those that do not;

 

(C) explain the effect of translations, reflections over the x- or y-axis, and rotations limited to 90°, 180°, 270°, and 360° as applied to two-dimensional shapes on a coordinate plane using an algebraic representation; and

 

(D) model the effect on linear and area measurements of dilated two-dimensional shapes.

8.11

Measurement and data. The student applies mathematical process standards to use statistical procedures to describe data. The student is expected to:

 

(A) construct a scatterplot and describe the observed data to address questions of association such as linear, non-linear, and no association between bivariate data;

 

(B) determine the mean absolute deviation and use this quantity as a measure of the average distance data are from the mean using a data set of no more than 10 data points; and

 

(C) simulate generating random samples of the same size from a population with known characteristics to develop the notion of a random sample being representative of the population from which it was selected.
