VISUALIZATION
Name the geometric term(s) for:
a paritally-opened news paper
woven threads in a piece of cloth
satellite dish signal
We'll be glad to check your answers.
plane
lines
lines
i think that's what they are..not sure
Does a partially opened newspaper look like this?

You're right about the fabric threads.

Here's a satellite dish signal picture. Do you see lines?

so...its lines, lines, and points?
Name an example that shows that three points are always coplanar, but four points are not always coplanor
To find the geometric terms for the given objects, we need to understand their shapes and forms. Let's analyze each object:
1. Partially-Opened Newspaper:
When a newspaper is partially opened, the shape it resembles is a cone. A cone is a three-dimensional geometric shape with a flat circular base and a pointed top, called the apex. The partially opened newspaper can be visualized as a cone lying on its side.
2. Woven Threads in a Piece of Cloth:
The woven threads in a piece of cloth form a pattern called a weave or a fabric weave. The weave refers to the way the threads are interlaced to create the fabric. There are various types of weaves, including plain weave, twill weave, satin weave, and more. The specific type of weave in a piece of cloth can determine its texture, strength, and appearance.
3. Satellite Dish Signal:
The shape of a satellite dish can be considered a parabolic reflector. It is a geometric shape known as a paraboloid, specifically a parabolic surface. A parabolic surface is a three-dimensional shape created by rotating a parabola around its axis. The satellite dish's parabolic shape helps it collect and reflect signals to and from satellites.
So, the geometric terms for the given objects are:
1. Partially-Opened Newspaper: Cone
2. Woven Threads in a Piece of Cloth: Weave or Fabric Weave
3. Satellite Dish Signal: Parabolic Reflector, Paraboloid
These terms help describe the shapes and structures of the objects in question.
