QUESTION:
The intersection of longitude line and latitude line.
CHOICES:
A. point
B. Line
C. Plane
ANSWER:
- It's none of the above. The actual answer is GRATICULE.
REASON:
(I'll give the meaning of Point, line and plane.)
POINT
ILLUSTRATION:
HOW TO NAME:
- In naming a point, we use capital letters •A
- Read as: Point A
DIFINITION:
- A point is an exact position or location on a plane surface. It has no length, width, or thickness. Also, all of the figures in geometry are made up of points.
LINE
ILLUSTRATION:
- Straight mark and has two arrow heads on opposite ends. The arrow heads indicate that it can be extended indefinitely.
HOW TO NAME:
- In naming a line, we use two capital letters with a double arrowhead above them or a lower-case letter.
DIFINITION:
- Just like the point, a line has no width and thickness, but it has infinite length because a line consists of infinitely many points. Also, two points can determine a line, that is, we can draw a line using two points.
PLANE
ILLUSTRATION:
- Slanted four-sided figure. (See the picture above)
HOW TO NAME:
- A plane ca be name using three capital letters formed by three noncollinear points.
DIFINITION:
- A plane is a flat surface that extends infinitely in all directions. It has infinite length and width but has no thickness. A plane is named by three points in the plane that are not on the same line.
