The word dodecagon comes from the Greek words dōdeka meaning twelve, and gon meaning sides. A dodecagon is a two-dimensional geometric shape with twelve straight sides, twelve angles, and twelve vertices. When all the sides and angles are equal, it’s called a regular dodecagon. These 12-sided shapes appear not only in geometry textbooks but also …
Non-collinear points are a set of three or more points that do not fall on the same straight line. In other words, they are not in a straight line and cannot be connected by drawing a single straight line through all of them. For example, imagine three dots randomly placed on a piece of paper. …
Collinear points are a fundamental geometry concept often used to prove theorems and solve problems. By definition, collinear points are points that lie on the same line. This means if you draw a straight line connecting any of these points, it will pass through the other points. One of the most essential properties of collinear …
An angle is one of the fundamental aspects of geometry, and it plays a crucial role in shaping the world around us. Corresponding angles, in particular, are a critical concept in geometry that can help us understand how different objects interact. What are Corresponding Angles? Corresponding angles are formed when a third line, known as …
If you are a fan of indoor games like me, you must have come across cubes such as dice and Rubix cubes. If you are not a fan, you may have used or seen ice cubes, milk crates, solid square tables, and many other objects with cubic shapes. What is a cube? The term cube …
We come across intersecting lines every day. However, if you take a closer look at two intersecting straight lines, you will notice something interesting: four angles are formed when two straight lines intersect. You will also notice that the two opposite angles are equal. The two intersecting lines form two pairs of vertical angles. Vertical …
Angles are those spaces formed between two intersecting lines. They are measured in degrees. Angles make up part of many structures and shapes in the world around us. Supplementary angles in geometry are angles whose sum is 180 degrees. These angles, therefore, form a straight line when joined together. However, they do not have to …
Angles are everywhere around us. They form part of the basic structure of many of the shapes that we encounter in our daily lives. Adjacent angles are angles that share a common vertex and arm or side and do not overlap. They instead lie on opposite sides of the arm they share. When two non-common …
The relationship between two variables can be represented graphically. When the rate of change for both variables is constant, the relationship between these two variables is represented by a straight line. When the rate of change is constantly varying, the relationship between the two variables is represented graphically by a curve. Instantaneous rate of change …
Similarity statements are logical arguments that show how two or more shapes are similar. They focus on two things: the lengths of the sides and angle measures in the two shapes. The similarity comes from the fact that two figures are identical in shape but differ in size. This is due to a scale factor …
