DIRECTIONS:
Directions are part of logical reasoning. It is one of the most commonly found topics in almost all the entrance exams. The topic requires analytical and logical skills to solve the questions.
👉POINTS TO REMEMBER👈
-
TYPES OF DIRECTIONS: There are 4 main directions and 4 cardinal directions. The main directions are; East, West, North, and South, whereas the cardinal directions are: North-East, North-West, South-East, and South-West.
-
CLOCKWISE / ANTI-CLOCKWISE: If we move to the right, the entire direction will be clockwise. So, every right movement will lead to the East, South, and West directions, which are clockwise when starting from the right point, at North. Similarly, if the movement begins from the left, the entire directions that follow would be anti-clockwise. So, if you turn to the left from North, the directions would be West, South, and East, which are in a reverse pattern.
-
PYTHAGORAS THEOREM: The concept of Pythagoras theorem is highly applicable in direction reasoning problem. In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. i.e., c2 = a2 + b2.
-
ANGLES:The first point you need to remember is that each main direction change undergoes a 90° change in direction e.g. from North to West/East it will be 90° change. But the change between North and North-east is only 45°.
-
SHADOW:In the morning, as the sun rises from the east, so the shadow of any objects formed is in the west direction.
At noon, or 12 pm, when the sun is exactly on top , no shadow will form.
In the evening , as the sun sets in the West , so the shadow of any objects formed is in the East.
Keeping these directions in mind, there are some types of questions which come into the exams, which we will discuss one by one.
