What is an infinite one dimensional figure?
A line is a one-dimensional figure that is made up of an infinite number of individual points placed side by side. In geometry all lines are assumed to be straight; if they bend they are called a curve. A line continues infinitely in two directions.
Is a line one dimensional and have infinite length?
A line extends indefinitely in a single dimension. Its length, having no limit, is infinite. Like the line segments that constitute it, it has no width or height.
Which of the following are three dimensional?
Learn with the Complete K-5 Math Learning Program The attributes of a three-dimensional figure are faces, edges and vertices. The three dimensions compose the edges of a 3D geometric shape. A cube, rectangular prism, sphere, cone and cylinder are the basic 3-dimensional shapes we see around us.
How do ants see the world?
Ants’ eyes are not like ours. Ants have compound eyes with many units, called ommatidia. Their eyes look like an array of LEDs you’d see in a traffic light (except in a dome shape). Each ommatidium sees one point in space so the whole eye sees one image but different portions of it.
Why ants kill their queen?
“The main advantage is to allow your sister workers to lay male eggs, rather than the queen, who typically stops worker reproduction by egg eating, attacking reproducing workers, and by laying many of her own eggs. By eliminating the queen, a matricidal worker allows other workers and herself to lay male eggs.”
