Question

how many planes appear in the figure? name a point non - coplanar to plane z. name the intersection of plane jps and plane z.

Explanation:

Step1: Count the planes

Count the distinct flat - surfaces in the figure. We can see that plane JPS and plane Z are two of the planes. There are also other planes formed by the faces of the rectangular - like solid. In total, we can identify 3 planes: plane JPS, plane Z, and the plane formed by the front - face of the solid (not named).

Step2: Find non - coplanar point

A non - coplanar point to plane Z means a point that does not lie on plane Z. Point P lies on plane JPS but not on plane Z.

Step3: Find intersection

The intersection of two non - parallel planes is a line. Looking at plane JPS and plane Z, their intersection is line LS.

Answer:

1. 3 planes appear in the figure.
2. Point P is non - coplanar to plane Z.
3. The intersection of plane JPS and plane Z is line LS.
