14 best compass for geometry and protractor
A compass and a protractor are essential drafting tools used in geometry, mathematics, and various technical and educational applications. They are commonly found in drafting tool kits, teaching materials, and office and school supplies. Here's what you need to know about each of these tools:
1. Compass:
- Purpose: A compass is a drawing tool with two adjustable legs that are joined at a hinge. It is primarily used for drawing circles and arcs of specific sizes and radii.
- Components: Compasses typically consist of two arms or legs, one with a pointed end for marking the center of the circle and the other with a pencil or pen attachment for drawing.
- Adjustability: Compasses have a mechanism for adjusting the distance between the legs, allowing you to create circles of various diameters.
- Applications: Compasses are used in geometry to construct circles, bisect angles, and perform various geometric constructions. They are also used in art and design for precise circular drawings.
- Materials: Compasses are commonly made of metal, plastic, or a combination of both. Some high-quality compasses have additional features such as a locking mechanism for maintaining a constant radius while drawing.
2. Protractor:
- Purpose: A protractor is a measuring tool used to measure and draw angles. It typically consists of a half-circle or full-circle scale marked in degrees.
- Components: Protractors come in various shapes, including semicircular and circular designs. They have a center point (or vertex) and a scale along the curved edge, marked in degrees from 0 to 180 or 0 to 360, depending on the type.
- Measurement: To measure an angle, you place the protractor's center point at the vertex of the angle and align the base of the protractor with one side of the angle. The degree reading where the other side of the angle intersects the scale indicates the measure of the angle.
- Applications: Protractors are essential in geometry and trigonometry for measuring and drawing angles accurately.They are commonly used in mathematics classes, architectural and engineering drafting, and various technical fields.
- Materials: Protractors are typically made of transparent plastic, clear acrylic, or metal. Some protractors have additional features, such as angle conversion tables or rulers along the straight edge.
Both compasses and protractors are indispensable tools for students, teachers, engineers, architects, and anyone involved in geometry, technical drawing, or related fields. They help ensure precision and accuracy when working with shapes, angles, and geometric constructions. These tools can be purchased individually or as part of drafting tool kits and educational materials.

User questions & answers
Question: | Is this a suitable kit to substitute for an oxford geometry set |
Answer: | Yes, it's very similar: Compact, comprehensive set includes metal compass with pencil holder, metal compass with lead, pencil sharpener, eraser, pencil, ruler, protractor, a set of squares, and one pack of leads. Packed in a reusable plastic storage box.Item PropertiesCategory: Drawing InstrumentsCategory: Ruling & Measuring ToolsBrand: Maped®Type: Drawing and Geometry Set |
Question: | what size lead does the compass use |
Answer: | 2mm diameter lead... 2mm in diameter - 16mm in length. The compass needs at least a millimeter of lead in the retainer part to be able to hold onto the lead, and that means that about 5mm of the lead is wasted. |
Question: | does the compass lock in place |
Answer: | There are some locking compasses that I found on Amazon. They are as follows:Helix Large Plastic Locking Compass and Safety Point, Assorted (37279), Staedtler Masterbow Comfort Student Compass for Circles to 10.25 Inch Diameter, Lead and Pouch (551-40-WP), Helix Plastic Locking Compass, Red/Black (33325), and Maped Stop System Compass with Pencil, Red (196510). there may be others. just search for "locking compass" in the search bar. |
Question: | What's the biggest circle size you can make with this |
Answer: | 12.25 inches |

User questions & answers
Question: | Where is it manufactured |
Answer: | china |
Question: | Will this punch holes in the paper |
Answer: | No, it doesn't 'punch' holes, but it will made a very small divot. The point is very sharp and if on a solid backing it only leaves a tiny divot that can be seen if looked for. Sometimes it's important so that the center can be found for other measurements & drawing. |
Question: | Will this hold different size pencils or markers |
Answer: | The holder works with any standard sized pencil or pen, but will not work with Jumbo or other oversized writing instruments |

User questions & answers
Question: | Does the protractor have a hole in it? Required for the school supply list |
Answer: | Yes, it has a hole in the center |
Question: | Is the protractor clear white or transparent purple |
Answer: | Mine was clear white |
Question: | will the pencil holder angle enough to draw a circle on a tennis ball |
Answer: | I bet it would. Just extend the pencil as far in the grip part. If that doesn’t work a #2 Pencil |
Question: | Could I use a sharpie with this |
Answer: | No. It's designed for pencil size writing instruments. I don't recommend it anyway. I used it twice and threw it out, and bit the bullet to buy a good drafting compass. This does not hold its position well. I use it for Zentangle, drawing mandalas, not for anything hugely precise, but this was useless. |

User questions & answers
Question: | Does the compass stay in position well? I need one that will stay at a fixed diameter and allow me to move the whole compass without changing the diam |
Answer: | The two compasses seem to stay in position pretty well as long as you don't push extremely hard. You can lightly outline a circle or arc with a compass and then go back over it again freehand to make it darker. They also have a screw allowing you to tighten them so you could probably apply more pressure that way. I feel they stay fixed well enough. |
