No
give 3 axes to object, setup the x,y,z system, then rotate along the x means roll, along y means pitch and along z means yaw
Try and show this as well as you can: Think of a wheel, or whatever that is cylinder-shaped. One point on the wheel's base is our aim of attention. If you look at the wheel from the side, and roll it at a constant speed, one point on the wheel makes a sine curve. You could illustrate by adding something that leaves a trail to a cylinder. Like gluing a piece of chalk on a scroll of tape. Then roll the scroll next to a blackboard, and the result should be a sine curve, where the amplitude is the same as the radius of the scroll.
First, tell him you're gay. If he dumps you, he wasn't much of a friend. If he stays your friend, tell him you'd like to give him head, if he's willing. If he says no, don't press it. A good friend is worth more than a quick roll in the hay.
A pyramid will not roll and you cannot stack objects on top.
The square based pyramid does not stack or roll.
no
A cylinder

a pyramid and a cone are alike because they both have a flat side on the bottom and they can slide. they are different because a pyramid has 5 flat sides on the sides and 1 flat side on the bottom part. a cone can roll but a pyramid can't roll like the cone.
no
slide
Slide.
Yes
