Which geometrical instrument is used to construct a square?
Answers
More commonly the set square bears the markings of a ruler and a half circle protractor. The outer edges are typically bevelled. These set squares come in two usual forms, both right triangles: one with 90-45-45 degree angles, the other with 30-60-90 degree angles.
Concept:
This question requires the concept of geometry from the construction portion.
Construction in geometry is the action of building geometrical figures like squares, rectangles and circles.
To find:
We are asked to find the geometrical instrument which is required to construct a square.
Solution:
The instruments required will be a ruler, compass, pencil, paper and eraser.
Steps for construction:
1. Draw a line segment of cm units name it AB
2. At point A, make a 90° angle using your compass and draw a line vertically through that point of the same cm units, name ie AC
3. Again At C, make a 90° angle and draw a horizontal line of the same cm units as line segment ABn name it CD.
4. Then, join the line from point B to D forming the line segment BD
Your, required square named ABCD is constructed using the instruments above.
Conclusion:
Instruments required: ruler, compass, pencil, paper and eraser.
