This 8 page pdf document takes you through constructions of parallelograms, Equilateral Triangles, Isosceles Triangles, Enlargements, Centroids of Triangles, Circumcentre and Circumcircle of Triangles and Incentre and Incircle of Triangles.
This 7 page pdf document looks at: The Coordinate Plane, Line segments, Lengths, Midpoints, Points of Intersection, Slopes of Lines, The Use of Sliders for Dynamic Line Presentations, Drawing Triangles, Finding Areas, and Translations.
This 8 page pdf document looks at: Demonstrate the Defintion of a Circle, Plotting Dynamic Circles, Intersection of Lines and Circles, Equations of Tangents to Circles, Transformation of the Circle, and Examining Theorem 20.
This 6 page pdf document looks at: Plotting Trigonometric Functions, Changing From Radians to Degrees, Plotting Dynamic Fuctions of y = asinbx and y = acosbx, and Creating a Dynamic Worksheet.
