What are the basic geometric construction?
Geometric construction is the process of drawing a geometrical figure using two geometrical instruments, a compass, and a ruler. We use a compass to draw arcs and circles and mark off equal lengths. We use a ruler to draw line segments and measure their lengths.
What are the types of geometric construction?
Types of constructions geometry
- Bisections. Using just a compass and a ruler, we can cut a line or angle in half.
- Copies.
- Angles.
- Triangles.
- Other Shapes.

How do you do construction in geometry?
Construction Steps
- Draw segment a = AB between points A and B.
- Construct perpendicular line b to segment AB through point B.
- Construct circle c with center B through point A.
- Intersect circle c with perpendicular line b to get intersection point C.
- Construct perpendicular line d to segment AB through point A.
What is geometrical drawing construction?
Geometric construction refers to the process of drawing lines, angles, and other geometric shapes and figures using only a compass and a straightedge (usually a ruler without measurements), without use of specific measurements of length, angle, etc.
How does a geometric construction differ from a drawing?
Answer Expert Verified The difference between constructing and drawing geometric figures is that when constructing a geometric figure, you use compass, protractor, ruler, or any scale with accurate measurement while when drawing geometric figures, you just draw with free-hand.
What is geometric construction?
Definition of geometrical construction : construction employing only straightedge and compasses or effected by drawing only straight lines and circles —opposed to mechanical construction.
What are examples of constructions?
The definition of construction is the process of making something, the occupation of building or the way that something is put together. An example of construction is the creating and decorating of a new ice cream shoppe in a store that previously was a shoe store.
What does construction mean in geometry?
Construction is the drawing of geometric shapes accurately and with the help of mathematical instruments like the compass, ruler etc. Constructing a line parallel to a given line is perfectly easy.
What do you need to know about geometric constructions?
Geometric constructions are shapes, angles, and lines that are drawn using a compass, a ruler, and a pencil. These projects provide opportunities for students to learn about and create geometric constructions. Geometric constructions have been a part of geometry instruction since Euclid wrote the first geometry book thousands of years ago.
What is the rubric for geometry construction project?
Geometry Construction Project Grading Rubric Creativity: 16-20 •Original design is very clever; creatively designed •Original design is either completely original or combines non-original designs in an original way. •Coloring, etc. on all designs is creative and shows care and creativity.
What makes a 16-20 geometry construction well made?
16-20 •Erasures are well made..there is little to no evidence of original construction marks. •There are no smudges. •Coloring is neatly done and is pleasing to the eye.
How are compass and straightedge used in geometry?
Constructions using compass and straightedge have a long history in Euclidean geometry. Their use reflects the basic axioms of this system. However, the stipulation that these be the only tools used in a construction is artificial and only has meaning if one views the process of construction as an application of logic.
