A point is the fundamental element of geometry. If we put the tip of a pencil on a paper and press it lightly, we see a very small mark on the paper. ... It is called a point.]]> 2021-06-11 16:36:56 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601483988 Plane gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601496935 Piece of paper 
In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far. While a piece of paper is a flat, and double sided sheet. ]]> 2021-06-11 16:42:49 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601496935 Coplanar Points gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601507444 Pool Table
When you play pool, the pool table would be the plane and the balls would be the different points and this is coplanar because the balls lie in the same plane (the table) and majority of them (balls) are in common places.]]> 2021-06-11 16:47:41 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601507444 Collinear Points gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601519979 Football players on the line of scrimmage are collinear. This is because multiple people are lined up next to each other forming a line with multiple points. ]]> 2021-06-11 16:52:32 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601519979 Line gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601528696 The Equator 
The equator is an example of a great circle. The line through the centre of the sphere perpendicular to the plane of a great circle meets the sphere in two points called the poles of the great circle.]]> 2021-06-11 16:56:27 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601528696 Line Segment gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601533333 Pencil
A line segment is one-dimensional. It has a measurable length, but has zero width. If you draw a line segment with a pencil, examination with a microscope would show that the pencil mark has a measurable width. The pencil line is just a way to illustrate the idea on paper.]]> 2021-06-11 16:58:34 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601533333 If two distinct lines intersect then they intersect in exactly one point gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601599119 An X
An X is an example of this because it is two lines that intersect in the center. ]]> 2021-06-11 17:27:57 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601599119 Parallel Lines gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601603912 Legs 
Legs are an example of parallel lines because it is two lines that lie in the same plane that never intersect or meet each other. ]]> 2021-06-11 17:29:55 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601603912 If two distinct lines intersect then they intersect in exactly one line gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601611998 People standing next to each other
This is an example of two distinct lines in one line because it is two points next to each other creating a line. ]]> 2021-06-11 17:33:35 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601611998 Obtuse Angle gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601626059 An open fan
An open fan is an example of an obtuse angle because it is open to a 180 degree angle. ]]> 2021-06-11 17:40:34 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601626059 Acute Angle gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601632680 A pizza slice
This is an acute angle because if we slice a pizza into 5 or more slices, each slice of pizza will make an acute angle. Each slice of the pizza makes an acute angle. ]]> 2021-06-11 17:43:49 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601632680 Right Angle gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601658481 A ruler is an example of a right angle because it has a 90 degree angle in the corner. ]]> 2021-06-11 17:56:35 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601658481 Rectangle gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601685579 A white board
This is an example of a rectangle because it is a four sided flat shape with all interior angles are right angles.]]> 2021-06-11 18:11:44 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601685579 Triangle gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601691079 A pyramid

These are congruent segments because they all have the same length even if they don't have to be parallel. ]]> 2021-06-11 18:28:22 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601714639 Circle gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601721811 A coin
A coin is an example of a circle because it has no end. Circles are simply closed curves equidistant from a fixed center. Circles are special ellipses that have a single constant radius around a center.]]> 2021-06-11 18:32:57 UTC https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601721811 Perimeter gracecartwright23 https://padlet.com/gracecartwright23/5le14zz9zqqjsoh0/wish/1601729436 A house
