What is the distance formula?

1)What are corresponding angles?
2) What are vertical angles?
1) Corresponding angles are the angles that are formed when two parallel lines are intersected by the transversal. These are formed in the matching corners or corresponding corners with the transversal.
2) each of the pairs of opposite angles made by two intersecting lines

Whats is a rigid motion?
A transformation of the plane that preserves length and angle measure. Reflections, translations, rotations, and compositions are "rigid motions".

What is a composition??
A composition of transformations is a combination of two or more transformations, each performed on the previous image.
