This book contains 18 sets of activities focusing on congruence, similarity, right triangles, trigonometry, circles and expressing geometric properties with equations. The activities consist of four different stations where students work in small groups, moving from station to station once their activities are complete. Contents: Congruence -- Set 1: Parallel Line and Transversals -- Set 2: Classifying triangles and Angle Theorems -- Set 3: Corresponding Parts, Transformations, and Proof -- Set 4: Special Congruent Triangles -- Set 5: Bisectors, Medians, and Altitudes -- Set 6: Triangle Inequalities -- Set 7: Translations, Dilations, Tessellations, and Symmetry -- Set 8: Coordinate Proof -- Set 9: Rhombi, Squares, Kites, and Trapezoids -- Similarity, Right Triangles, and Trigonometry -- Set 1: Similarity and Scale Factor -- Set 2: Ratio Segments -- Sine, Cosine, and Tangent Ratios, and Angels of Elevation and Depression -- Circles -- Set 1: Circumference, Angles, Arcs, Chords, and Inscribed.
