Question

Find the minimum number of straight lines required to make the given figure. 

• A. 15
• B. 16
• C. 17
• D. 18
• E. 19

Hint:

To ensure accuracy, trace each line with a pencil (or your finger) from one end to the other. If you don't have to lift your finger or change direction, it counts as exactly one straight line.

Answer 1

The Correct Option is C

To solve the problem of finding the minimum number of straight lines required to construct the given figure, we need to carefully analyze the structure and count the lines without missing any.

1. Start by identifying all the unique straight lines in the figure. Begin at one corner or point and systematically move around the figure to ensure all lines are counted.
2. Consider the main large shapes first, such as rectangles or triangles, and count their lines.
3. Look for lines that may overlap or intersect inside the figure, as these sometimes are easy to miss when counting.
4. Re-check each segment of the structure to make sure no line is counted more than once.
5. In this figure, we have:
   • 6 lines forming the outer rectangle.
   • 5 lines forming the top triangle section.
   • 6 lines forming intersecting sections within the inner shapes.
6. Add up the lines for the total count: \(6 + 5 + 6 = 17\).

The minimum number of straight lines required to create the figure is 17. Therefore, the correct answer is the option labeled 17.
