This program helps students
understand the concept of an angle through testing their knowledge
of sizes of angles, the definitions of certain sized angles and
the ability to locate angles relating to parallel lines.
Starting from estimation of sizes of angles, this program develops
students' angle knowledge giving them greater confidence when calculating
with angles and understanding more complex geometrical diagrams.
Choice of either estimating an angle's size from a given diagram
or drawing a diagram from a given angle
> Choice of either to name or draw acute, obtuse and reflex angles
as well as complementary and supplementary angles.
> Choice to find alternate, corresponding, vertically opposite
and supplementary angles using 3 letter notation on a diagram of
> After selecting the chosen options, 10 questions are asked,
with scores given for accuracy of answers.
> Students can reattempt questions if they were not sufficiently
close. Guidance is given by the program whether to go larger or
> The labelling of the vertices in displayed parallel lines diagram
changes with each question, to keep testing their knowledge of 3
