Answers. Best Answer: A delta is formed when a high flow water body meets a low flow one. Meaning, when a river meets a lake or ocean. The river carries sediment because of it's high energy (flow). When it suddenly slows down the sediment drops out all at once and a delta forms.est Answer: A delta is formed when a high flow water body meets a low flow one.

Two lines are said to be intersecting lines if they have a common point. It is to be noted that if two straight lines intersect each other, they can intersect at exactly point and that point is said to be the intersecting point of those two lines. In the figure, there are two lines $\overleftrightarrow{AB}$ and $\overleftrightarrow{CD}$ are two straight lines and P is a common point.
Answer: When a transversal cuts (or intersects) parallel lines several pairs of congruent and supplementary angles are formed. There are 3 types of angles that are congruent: Alternate Interior, Alternate Exterior and Corresponding Angles. Some people find it helpful to use the 'Z test ' for alternate interior angles. If you can draw a Z or a 'backwards z', then the alternate interior angles are the ones that are in the corners of the Z.
