This program provides students with a lively introduction to key concepts involved with angles, such as how we define and write information about an angle, mathematical notation for rays, line segments and lines, and how to use a protractor. Obtuse and acute angles are illustrated, the relationships between the angles formed by a transversal crossing parallel lines are investigated and congruent triangles are introduced, all using examples from real life, supplemented by clear graphic overlays and simple animations.
