TLE: MEASURING TOOLS

• Measuring tools are vital in producing quality output.
• Compass- this tool is used for scribing or drawing arcs, circles, parts of many symbols and radii.
• this is like the compass construction. As the name implies, divider is used for diving distances into several equal parts by the trial-and-error method.
• Protractor- it is used for laying out angles and measuring and setting of angles other than those obtainable with the triangles
• Ruler- is the most popular type of measuring tool. It is usually 6 to 12 inches in length. It is needed for measuring sizes and distances. It is also used to measure things that are small. Most rulers show customary units of measurement like inches and metric units of measurement such as millimeter and centimeter
• Tape or tape ruler- is a concave, spring-steel blade ranging from 1/4" to 1" wide and 6 to about 300 feet in length, coiled inside a carrying case. Metric tape ruler comes in comparable widths and lengths up to 10 meters. It provides an easy means for accurately measuring curved surfaces.
• Triangles- are used for drawing vertical and oblique lines. The most used triangles are the 450 and 300 x 600. The illustration shows the proper use of drawing lines and measuring angles using the T-square and triangle.
• T-square is used as a guide in drawing horizontal lines and in measuring up to 48" straight line.
• Tape measure- it used to measure length. They are used to measure many of the distances that are too long for a ruler to measure easily and they are flexible, not rigid.
• Yard stick/ meter stick yard/meter and shows only it measures one metric units of measurement of feet, inches, centimeters, and millimeters. It used to measure objects that are larger than a piece of paper.
• Geometric shapes can be defined as figure or area closed by a boundary which is created by combining the specific number of curves, points, and lines.
• Circle- is a shape that can be made by tracing curve that is always the same distance from a point that we call the center.
• Triangle- is a shape that is formed by three straight lines that are called sides
• Rectangle- is a shape that has four sides. The distinguishing characteristic of a rectangle is that all four angles measure 90 degrees.
• Rhombus- is a shape formed by four straight lines. Its sides measure the same length but unlike the rectangle, any of all angles measure 90 degrees.
• Square- is a type of rectangle, but also a type of rhombus. It has characteristics of both.
