How many of you use geometry terms and definitions in your daily conversations? For that matter how many of you remember geometry class, much less the words associated with the subject. You might want to brush up on geometry skills, because if you have a child they might need help. Who are they going ask for help? That is right, you! So get prepared for the wonderful world that is geometry.
For all of you who would like a little assistance or a refresher course on geometry terms, then you have come to the right place. Helping with the concepts of geometry, we will leave that to the experts. The following is a list of common geometry terms and their definitions you may have all forgotten around the time you left geometry class for the last time in sophomore or junior year. So let the fun begin!
Common Geometry Terms and Their Definitions
- Point – This refers to a location in space or a dot on a piece of paper.
- Line – A line is what connects two points together at the shortest distance, which will then continue on forever.
- Line Segment – This refers to the line between two points. Hence the words segment.
- Perpendicular Line Segment – This is a line segment that crosses at an angle of 90 degrees.
- Parallel Line Segments – A line segment that never touches one another. However, these lines always run the same distance apart from one another.
- Right Angle - An angle that measures 90 degrees.
- Acute Angle – This is an angle that measures less than 90 degrees.
- Obtuse Angle - This type of angle measures more than 90 degrees.
- Vertex Point - This is where two line segments intersect or meet forming an angle.
- Scalene Triangle –A triangle with this name is none other than a triangle that has three sides and all three of them have different lengths.
- Isosceles Triangle – This triangle has two even proportioned sides, which also have two equal internal angles.
- Equilateral Triangle – This type of triangle has three sides and they are all equal. The internal angles of this type of triangle all also equal, with the same angle of 60 degrees.
- Radius Distance – This refers to a line segment that is coming from the center of a circle ending at any point on the circle’s circumference.
- Diameter – This refers to a line segment or the length that joins two points on a circle’s circumference that passes through the circle’s center. The diameter is twice the length of the radius.
- Circumference – This refers to the distance around a circle or what is known as circle’s perimeter.
- Chord - A line segment that joins two points on a curve.
- Arc - This refers to a part of a curve.
Now that you have come in contact with some common geometry terms and their definitions do you remember any of them? Do any of them ring a bell or was a bell what you were waiting on when geometry class started so you could run away from all the shapes. Triangles, Circles, and Angles, Oh, my!
If you do remember, then this may have been the refresher that you needed to be able to help your son or daughter out in their geometry class. If you still seem a little rusty then you can always pick up geometry as a hobby to relearn with your high school child. Try playing a few games from the Internet that reforce the geometry lessons. Playing together could give you and them a time to bond over something on which you are both not big fans. Therefore, you would not only be helping with geometry but with a life lesson that we all must do things from time to time that we do not particularly like.
