\n In the MagicGraph, you see a pair of parallel lines (shown in blue). These lines are intersected by line AB (shown in red). Line AB is called a transversal. The angles α and β are a pair of alternate interior angles formed by transversal AB.
\r\n The points A and B can moved interactively. No matter the location of points A and B, the two alternate interior angles always remain equal to each other. This property is called equality of alternate interior angles.\r\n
\r\n This MagicGraph is a visually interactive demo of equality of alternate interior angles. Tap on button to interactively move points A and B.\r\n Tap on button to pause points A and B.\r\n
