The applet below allows students to explore Complementary and Supplementary angles.

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

Note:
The Complementary Angles construction holds only when 0≤α≤90° and when 0≤β≤90° .
The Supplementary Angles construction holds only when 0≤γ≤180° and 0≤δ≤180°.
