За кои четири точки се веки дека се компланарни?
- A.
точките од кои две по две лежат на две рамнини
- B.
точките кои лежат на иста права
- C.
точките кои лежат во иста рамнина
- D.
точките од кои две по две лежат на две разминувачки прави
Correct Answer
C. точките кои лежат во иста рамнинаExplanation
The correct answer is "точките кои лежат во иста рамнина" which translates to "the points that lie in the same plane." This means that the given points are all located in the same two-dimensional surface.Rate this question:

Колку најмногу прави може да се определат со точките A,B,C,D,E ако кои било три од нив не се колинеарни
- A.
4
- B.
8
- C.

12
Correct Answer
C. 10Explanation
If any three points are not collinear, then they can form a triangle. In a triangle, the maximum number of sides or lines that can be formed is 3. Therefore, with the given points A, B, C, D, E, the maximum number of lines that can be formed is 3. Each line is formed by connecting two points. So, the maximum number of lines or sides that can be formed is 3, which means the answer is 10.Rate this question:

Две прави да имаат само две заеднички (различни ) точки
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement says that two lines should have only two common points, which are different from each other. This statement is false because two lines can have either no common points, one common point, or infinitely many common points. It is not necessary for two lines to have exactly two distinct common points. Therefore, the correct answer is false.Rate this question:

Правите a и b не се сечат. Тогаш тие може да не лежат во иста рамнина?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
If the lines a and b do not intersect, it means that they do not cross each other or share a common point. In this case, it is possible for them to not lie in the same plane. This is because planes are infinite and can exist in three-dimensional space, while lines can be contained within a plane or extend beyond it. Therefore, the statement "they may not lie in the same plane" is true.Rate this question:

Точката А лежи во рамнината .Тогаш правата што минува низ таа точка може да лежи во рамнината.
- A.
да
- B.
не
Correct Answer
A. даExplanation
In the given statement, it is mentioned that point A lies in the plane. Therefore, any line passing through point A will also lie in the same plane. This is because a plane is a two-dimensional surface that extends infinitely in all directions, and any line passing through a point in that plane will also lie within that plane. Hence, the answer is "да" (yes).Rate this question:

Колку рамнини определуваат три прави кои минуваат низ иста точка
Correct Answer
3Explanation
The question is asking how many planes can be determined by three lines passing through the same point. In three-dimensional space, three non-parallel lines passing through the same point will determine a unique plane. Therefore, the correct answer is 3.Rate this question:

На цртежот е претставен квадар ABCDEFGH. Правата EF го содржи работ EF. Кои прави се сечат со EF?
- A.
AE и HE
- B.
DE и GE
- C.
CF и DF
- D.
BF и GF
Correct Answer(s)
A. AE и HE
D. BF и GFExplanation
The correct answer is AE и HE, BF и GF. In the given diagram, the line EF is shown passing through the points E and F. To determine which lines intersect with EF, we need to identify the lines that also pass through points A, H, B, and G. From the options given, lines AE and HE both pass through point A and intersect with EF. Similarly, lines BF and GF both pass through point B and intersect with EF. Therefore, the correct answer is AE и HE, BF и GF.Rate this question:
