Question

name the plane that is highlighted in the diagram below.

Explanation:

Step1: Identify points on the plane

The highlighted plane contains points \( W \), \( Y \), \( U \), \( S \) (or other combinations like \( W \), \( Y \), \( U \), \( S \) as seen in the diagram's vertices on the plane). A plane can be named by three non - collinear points or four coplanar points. Looking at the diagram, the plane passes through points \( W \), \( Y \), \( U \), \( S \). We can name the plane using three of these points, for example, Plane \( WYU \) or Plane \( WYS \) or Plane \( WSU \) or Plane \( YSU \), but a common way is to use three non - collinear points. Another way is to use the four - point naming. But the standard way is to use three non - collinear points on the plane. From the diagram, the plane can be named as Plane \( WYS \) (or other valid combinations). But more accurately, looking at the vertices, the plane includes \( W \), \( Y \), \( U \), \( S \). So one valid name is Plane \( WYU \) or Plane \( WYS \) or Plane \( WSU \) or Plane \( YSU \). The most appropriate is to use three non - collinear points. Let's take \( W \), \( Y \), and \( S \) (or \( W \), \( Y \), \( U \)). Wait, actually, in the diagram, the plane is a quadrilateral with vertices \( W \), \( Y \), \( U \), \( S \). So the plane can be named as Plane \( WYUS \) or using three points like Plane \( WYU \), Plane \( WYS \), Plane \( WSU \), Plane \( YSU \). The correct way is to name the plane by three non - collinear points on it. So for example, Plane \( WYS \) (but let's check the points: \( W \), \( Y \), \( S \) – are they non - collinear? Yes. Alternatively, Plane \( WYU \): \( W \), \( Y \), \( U \) – non - collinear. But the standard method is to use three points. So the plane can be named as Plane \( WYS \) (or other valid combinations). Wait, actually, looking at the cube - like figure, the highlighted plane has points \( W \), \( Y \), \( U \), \( S \). So the plane is Plane \( WYUS \) or Plane \( WYU \) (using three points). But the correct answer is Plane \( WYUS \) (or any three non - collinear points on the plane, like Plane \( WYS \), Plane \( WYU \), Plane \( WSU \), Plane \( YSU \)). The most accurate is to use the four - point name or three non - collinear points. Let's confirm: in a plane, three non - collinear points define it. So taking points \( W \), \( Y \), and \( S \): \( W \) is connected to \( Y \), \( Y \) to \( U \), \( U \) to \( S \), \( S \) to \( W \)? Wait, no, in the diagram, \( W \) is connected to \( Z \), \( X \), \( S \); \( Y \) is connected to \( Z \), \( X \), \( U \); \( U \) is connected to \( X \), \( T \), \( V \); \( S \) is connected to \( T \), \( V \), \( W \). Wait, maybe I made a mistake. Let's re - examine: the highlighted plane – the blue plane. The vertices on the blue plane are \( W \), \( Y \), \( U \), \( S \). So the plane is Plane \( WYUS \). So we can name the plane as Plane \( WYUS \) (or using three points, e.g., Plane \( WYU \), Plane \( WYS \), Plane \( WSU \), Plane \( YSU \)). The correct answer is Plane \( WYUS \) (or any three non - collinear points from these four).

Answer:

Plane \( WYUS \) (or other valid names like Plane \( WYU \), Plane \( WYS \), Plane \( WSU \), Plane \( YSU \) based on the three - point naming convention for a plane)
