Question

the figure shown is a rectangular prism. which edges are perpendicular to ja? select each correct answer. jt ph tr ra ej

Explanation:

Step1: Recall perpendicular - edge property in rectangular prism

In a rectangular prism, edges that meet an edge at a right - angle are perpendicular to it.

Step2: Analyze the position of edges relative to $\overline{JA}$

For a rectangular prism, the edges that are perpendicular to an edge like $\overline{JA}$ are the ones that form right - angles with it. In a rectangular prism, the edges that are perpendicular to a given edge on the base are the vertical edges and the other base - edges that meet it at a right - angle.
The edges perpendicular to $\overline{JA}$ are $\overline{JT}$, $\overline{PH}$, $\overline{TR}$, $\overline{RA}$.

Answer:

$\overline{JT}$, $\overline{PH}$, $\overline{TR}$, $\overline{RA}$
