Students are asked to construct the bisectors of a given segment and a given angle and to justify one of the steps in each construction.

Students are asked to construct a line perpendicular to given line (1) through a point not on the line and (2) through a point on the line.

Explore the construction processes for constructing an angle bisector, copying an angle and constructing a line parallel to a given line through a point not on the line using a variety of tools in this interactive, retro video game-themed tutorial.

NOTE: This tutorial uses both the angle bisector construction and the construction to copy an angle as an extension opportunity to also construct a line parallel to a given line through a point not on the line. Students also learn to identify corresponding angles created when a transversal crosses parallel lines, and discover using Geogebra that these angles are congruent.
