What are parallel lines?
Lines that are always the same distance apart and never intersect.
How are parallel lines different from perpendicular lines?
Parallel lines never intersect, while perpendicular lines intersect to form right angles.

What is an angle?
The figure formed by two rays sharing a common endpoint.
What are perpendicular lines?
Lines that intersect to form a right angle.
What is the main difference between 2D and 3D shapes?
2D shapes are flat with only length and width, while 3D shapes are solid with length, width, and height.
Habitat
