Problem:

The problem involves finding the intersection between the planes $PQVW$ and $QRWT$ in a rectangular prism.

Key Concepts:

1. Planes in geometry are flat surfaces defined by three or more points.
2. The intersection of two planes in a rectangular prism usually forms a line.
3. The given planes:
   • Plane $PQVW$: Defined by points $P, Q, V, W$.
   • Plane $QRWT$: Defined by points $Q, R, W, T$.

Solution:

To determine the intersection:

• Both planes share points $Q$ and $W$.
• The line of intersection is line $QW$ since it's the common edge shared by these two planes.

Final Answer: Option (a) garis QW

Analysis of the Second Image (Latihan Mandiri 3 no 3)

Problem:

We are tasked to determine which statements are correct regarding point $A$, line $g$, and planes $\alpha$ and $\beta$. The problem provides four statements and asks for the correct combination.

Key Information:

1. $A$ is the intersection point of line $g$ and line $h$.
2. The statements involve checking whether $A$ lies on plane $\alpha$, plane $\beta$, or both, and if $g$ lies on either plane.

Evaluation of Statements:

1. (i) Point $A$ lies on plane $\alpha$.

   • From the diagram, $A$ is on the intersection of $\alpha$ and $\beta$, so this is true.

2. (ii) Point $A$ lies on plane $\beta$.

   • Same as above, $A$ is shared by
