**Geometry: ***Congruence, Similarity, Right Triangles, and Trigonometry, Circles, Expressing Geometric Properties with Equations, Geometric Measurement and Dimension.*

HMH-Fuse-Geometry- Free- This is a sample of the full app - relationships of angles, lines and planes (including rotations, translations and reflections) and to use geometric proofs, inductive and deductive reasoning. In addition to basic geometry theorems; solve problems relating to perimeters, circumference, area, volume and surface as well as study probability.

Right Angles Free - Know any two of the four values and it can give you a precise answer. Solve for Degree/Radian, Rise/Opposite, Base/Adjacent, Slope/Hypotenuse.

Euclid Geometric Constructions $.99 - Draw lines and intersect circles, create pentagons and compute square roots using a puzzle game format.

Geometry Stash $1.99 - Access the most commonly used theorems, postulates, and corollaries.

Trigonir $1.99 - Determine the following properties of trigonometric functions: domain and co domain of functions, zeros of functions, points where a function is not defined, increasing and decreasing of the function, positive/negative values, periodicity,evenness and oddness of a function, accurate value of basic angles, and properties of inverse functions (arcsin α, arccos α, arctan α, arccot α).

**Statistics and Probability- ***Interpreting Categorical and Quantitative Data, Making Inferences and Justifying Conclusions, Conditional Probability and the Rules of Probability, Using Probability to Make Decisions.*

Wolfram Statistics Course $1.99 - Create a bar chart, histogram, or scatter plot of any set of data. Find the mean, median, mode, standard deviation, quartiles, and interquartile range of a dataset. Calculate normal probabilities, binomial probabilities, compute probabilities based on dice rolls and coin flips and more.
