1. What are geometry and geometric constructions?

Geometry is a branch of Maths that primarily deals with sizes, shapes, and spaces. It has many subdivisions, and the major ones are:

**Plane Geometry -**You learn basic shapes such as points, lines, and various planes such as rectangles, squares, circles, triangles, etc.**Solid Geometry -**This deals with complicated calculations such as area, perimeter, volume, etc., of geometric figures. This also includes calculations of circle radii and arc lengths.

2. What are the steps of dividing a line segment of length l cms into a ratio of x:y?

The main steps in performing division of line segment in a given ratio are:

**Step 1 -**Draw a line PQ of length l cms.**Step 2 -**Draw a line PR of any length so that it makes an acute angle with the line segment PQ.**Step 3 -**On a compass use any small length to mark x+y number of points (p1, p2, p3, ….p(x+y)) of equal sizes on PR such that Pp1 = Pp2 = Pp3 = Pp4 = …= Pp(x+y)**Step 4 -**Join Q to Pp(x+y) to form line Qp(x+y)

Draw a line from point p1 to line PQ, which is parallel line Qp(x+y) and intersects PQ at point K. Now PK: KR = x:y.

3. What is a straightedge tool?

Straight edge tools are used for either drawing straight lines or checking how straight a line is. Any job that demands high accuracy is done by using the straight edge tool.
