A construction line is a line very lightly drawn and is used as a guide to help draw all other lines and shapes properly.
Medium solid line
In filipino language, a granil is "marking gauge" commonly used in woodworking or carpentry. As a tool, it can draw a straight line near the edge of the wood. During my grade school days I made one granil as my project in my carpentry subject. That started my passion for woodworking.
Alphabet of line is the usage of line types on a drawing. They are used to describe the various features of an object to the person reading the print.
An ellipsis is just a curve. Multiple ellipses in a vertical line may be used to form a sketch of a curved object.
ruler
A ruler.
First of all we can take a straight line,when we take a straight line we take a half circle in the left side of the line,then the end of a circle we take an CHAND and draw a 90 degree then it`s draw a root 2 we used this method we can easily draw a root 17.
Any "straightedge" whether it be the side of a book, piece of paper, etc. can be used to create a straight line. Rulers, are common straightedges, as they are tools specifically meant to draw and measure lines.
The straightedge can only be used to draw a straight line, or check to see if a surface is flat, but cannot measure length. A ruler can be used to draw a straight line or check for flatness, and a ruler can also measure length because it has evenly spaced markes denoting inches and centimeters.
A mirror image of an object is said to have a line of symmetry
A line graph is one where you plot your points then draw a smooth line through, or near, as many as possible. The line does not have to be straight. It's used to show the relationship between your two variables.
The compass is used to measure angles. The straightedge is used to draw a straight line. The two items together, are used to measure and draw angles and lines in geometric drawings.
a line used to mark the outside of an object
A ruler or straight edge.
An object moving in a straight line in science is typically referred to as a "particle." In physics, a particle is an idealized point-like object that exhibits motion along a single dimension without deviating from a straight path. This simple model is often used to study the motion of objects in various scientific disciplines.
The difference between an outline and a contour line is location. An outline is used to draw the outermost form on an object, while a contour line is used to depict details inside the form of an object.
