GeoGebra Constructions Organized by Strand

Geometry

Geometry - Parallel Lines and Transversal
  • Show the angle relationships associated with two parallel lines and a transversal
  • Show the naming of angle pairs formed by two lines and a transversal
Geometry - Triangles Sum of Angles
  • Show that the sum of interior angles in any triangle is 180 degrees
Trigonometry - Sine Law
  • Show the geometric implications of the Sine Law

Relations and Functions

Functions - Quadratic - Expanded Form
  • Show how the parameters in \( f(x)=ax^2+bx+c \) are related to the characteristics of the corresponding graph
Functions - Quadratic - Factored Form
  • Show how the parameters in \( f(x)=a(x−b)(x−c) \) are related to the characteristics of the corresponding graph
Relations - Domain and Range Shadows
  • Show that the range can be thought of as the shadow of the graph projected onto the y-axis
  • Show that the domain can be thought of as the shadow of the graph projected onto the x-axis
