Here is a toy with slanting slabs attached to its sides; the greater the angles or slopes of the slabs, the faster the balls roll. Can angles be used to describe the slopes of the slabs? What are the arms of each angle? Which arm is visible and which is not?

Angles describe the steepness of the toy’s slanting slabs. The base of the toy and the inclined slab edge form the arms of the angle, with the vertex where they meet. The visible arm is the slab’s slant, while the horizontal base is typically imaginary. A steeper angle leads to a faster roll due to gravity, making such toys useful in studying slopes, inclines, and the relationship between angles and motion.
