4. Perpendicular Lines (Classwork)

Interested participants may verify the relationships between slopes and

y-intercepts of two lines when they are perpendicular or parallel to each other.

5. Polygon&Triangles (Classwork)

Interested participants may observe how a quadrilateral (4-sided polygon) divides

itself into triangles.

6. Polygons&TheirDiagonals (Classwork)

Interested participants may observe that diagonals can be drawn from one vertex

of a polygon and the number of them is determined by the number of sides of the

polygon.

7. PolygonWorksheet (Classwork)

Interested participants may use this to investigate sum of interior angles of polygons

of different number of sides. Then make a general mathematical conjecture relating

them with each other.

8. TrianglesInteriorExteriorAngles (Classwork)

Interested participants may use this to see what happens to the sum of interior and

exterior angles when the triangle is altered by dragging any of its vertices.

9. LineOfBestFit

Interested participants may use this to draw the Line of Best Fit.
