If $$\displaystyle\mathsf{\overline{WS}}$$ ║ $$\displaystyle\mathsf{\overline{KV}}$$, and $$\displaystyle\mathsf{\overline{KV}}$$ ⊥ $$\displaystyle\mathsf{\overline{RT}}$$, then $$\displaystyle\mathsf{\overline{RT}}$$ ⊥ $$\displaystyle\mathsf{\overline{WS}}$$

Step-by-step explanation:

We are given the diagram of parallel lines, $$\displaystyle\mathsf{\overline{WS}}$$ and $$\displaystyle\mathsf{\overline{KV}}$$, which are intersected by line $$\displaystyle\mathsf{\overline{KV}}$$. The prompt requires us to determine the relationship between $$\displaystyle\mathsf{\overline{RT}}$$ and $$\displaystyle\mathsf{\overline{RS}}$$.

Definitions:

Parallel linesare non-intersecting lines that are coplanar and have the same slope.

Perpendicular lines: the intersection between two lines that form right angles. Perpendicular lines also have negative reciprocal slopes.

Transversal : a line that intersects at least two distinct coplanar lines in at least two or more definite points.

Explanation:

We will use the given diagram and the following theorems/postulates to prove the relationship between lines $$\displaystyle\mathsf{\overline{RT}}$$ and $$\displaystyle\mathsf{\overline{WS}}$$.

- The Parallel Postulate states that given line $$\displaystyle\mathsf{\overline{WS}}$$ and a point that is $$\displaystyle\sf\doubleunderline{\underline{\underline{not}}}$$ on line $$\displaystyle\mathsf{\overline{WS}}$$ , then there is exactly one line through that point that is parallel to line $$\displaystyle\mathsf{\overline{WS}}$$.
- The Perpendicular Postulate states that given line $$\displaystyle\mathsf{\overline{KV}}$$ and point R that is not on line $$\displaystyle\mathsf{\overline{KV}}$$, then there is a definite line through point R that is perpendicular to line $$\displaystyle\mathsf{\overline{KV}}$$.
- The Perpendicular Transversal Theorem states that given a transversal, $$\displaystyle\mathsf{\overline{RT}}$$, which is perpendicular to one of the parallel lines, $$\displaystyle\mathsf{\overline{WS}}$$, then it means that transversal $$\displaystyle\mathsf{\overline{RT}}$$ is also perpendicular to the other parallel line, $$\displaystyle\mathsf{\overline{KV}}$$.

Now that we have established the necessary postulates and theorem, we can state that:

- If $$\displaystyle\mathsf{\overline{WS}}$$ ║ $$\displaystyle\mathsf{\overline{KV}}$$, (Parallel Postulate) and $$\displaystyle\mathsf{\overline{KV}}$$ ⊥ $$\displaystyle\mathsf{\overline{RT}}$$, (Perpendicular Transversal Theorem ), then $$\displaystyle\mathsf{\overline{RT}}$$ ⊥ $$\displaystyle\mathsf{\overline{WS}}$$ (Perpendicular Postulate).
