## 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
