Abstract
A sample of 480 students from grades 2, 4, 6 and 8 were interviewed
concerning their recognition of abstract angles in nine familiar physical
situations. The major factor influencing students' interpretation of an angle
situation was not the number of arms of the abstract angle visible in the physical
situation. Even by the end of grade 8, many students had difficulty recognising angles
in situations where both arms of the angle were not visible. Implications are drawn
for the teaching of angles.
