This is a timed quiz to help recognize trigonometric functions. Random triangles are drawn with two sides highlighted, a red dashed line for the numerator and a solid green line for the denominator relative to the angle marked with the green arc. There is a requirement to get a number of correct answers before time runs out. The GeoGebra timer is not accurate but the correct time is shown in the summary.
There are matching quizzes for sine, cosine, and tangent and right triangle side definitions. The popup includes the name entered when the page loads, the quiz time, number correct, number wrong and date and time finished.
