  2. ACTIVITY 1 : TO IDENTIFY THE PLANE G H E F D C A B PLANE AT THE TOP : PLANE EFGH

  3. G H E F D C A B PLANE ON THE LEFT : PLANE ADHE

  4. G H E F D C A B PLANE IN THE FRONT : PLANE ABFE

  5. G H E F D C A B PLANE AT THE BACK : PLANE DCGH

  6. G H E F D C A B PLANE AT THE BOTTOM: PLANE ABCD

  7. G H E F D C A B PLANE ON THE RIGHT : PLANE BCGF

  8. THE LOCATION OF THE POINT ON TOP OF THE RED DOT TO THE RIGHT OF THE RED DOT AT THE BACK OF THE RED DOT IN FRONT OF THE RED DOT

  9. ON THE TOP OF …. AT THE BACKOF …. TO THE LEFT OF …. TO THE RIGHT OF …. IN FRONT OF …. AT THE BOTTOMOF ….

  10. H G E F D C A B ACTIVITY 2 : TO DETERMINE THE LOCATION OF A POINT POINT E POINT TO THELEFTOF F : POINT AT THE BOTTOM OF F : POINT B POINT AT THE BACK OF F : POINT G POINT TO THE RIGHT OF D : POINT C POINT ON TOP OF D : POINT H POINT IN FRONT OF D : POINT A

  11. ANGLE BETWEEN A LINE AND A PLANE A LINE PLANE B C

  12. Activity 3 :To Identify The Angle Between Line And Plane H G The line draw from G and perpendicular to the plane ABCD is call normal Normal E F D C The line lies on the plane ABCD which joint the point A to the line GC is known as the orthogonal projection of line AG on the plane ABCD. Orthogonal projection A B The angle between the line AG and the orthogonal projection, AC is the angle between the line AG and the plane ABCD that is GAC.

  13. ACTIVITY 3 : To Identify The Angle Between A Line And A Plane Example 1a H G C A G Normal E F D At the bottom C Name the angle between the line AG and the plane ABCD A B Orthogonal projection Angle between the line AG and the plane ABCD = GAC.
