Slope. I'm pretty sure.
When two lines are crossed by another line (called the Transversal): The angles in matching corners are called Corresponding Angles.
When two lines are crossed by another line (called the Transversal)
They don't always. When two lines are crossed by another line (called the transversal) the angles in matching corners are called corresponding angles. If the two lines being crossed are parallel lines, then (and only then) the corresponding angles are equal.
Proportional.
Always. If not, they are not called corresponding angles.

They are congruent triangles.
