3-4.4 Classify angles as either right, acute, or obtuse.

Angles (elementary)

Lesson: Students learn about classifying angles by their measure and in relation to angles formed by two lines crossed by a transversal.

3-4.6 Exemplify points, lines, line segments, rays, and angles.

Angles (elementary)	Lesson: Students learn about classifying angles by their measure and in relation to angles formed by two lines crossed by a transversal.
Lines, Rays, Line Segments, and Planes	Lesson: Introduces students to lines, rays, line segments, and planes.

3-4.8 Predict the results of one transformationâeither slide, flip, or turnâof a geometric shape.

Tessellations: Geometry and Symmetry	Lesson: Examines plane symmetry.
Translations, Reflections, and Rotations	Lesson: Introduces students to concepts of transformations.
Tessellate!	Activity: Create a tessellation by deforming a triangle, rectangle or hexagon to form a polygon that tiles the plane. Corners of the polygons may be dragged, and corresponding edges of the polygons may be dragged. Parameters: Colors, starting polygon.
Transmographer	Activity: Explore the world of translations, reflections, and rotations in the Cartesian coordinate system by performing transformations on squares, triangles and parallelograms. Parameters: Shape, x or y translation, reflections across vertical and horizontal lines, angle and point of rotation.
Transmographer 2	Activity: Build your own polygon and transform it in the Cartesian coordinate system. Experiment with reflections across any line, rotations about any point, and translations in any direction. Parameters: Shape, x or y translation, x or y reflection, angle of rotation
