Parallel lines in geometry are two or more straight lines in the same plane that never intersect, maintaining a consistent, equidistant relationship throughout their length, denoting no meeting point. When a line crosses two coplanar lines (lines lying on the same plane), it is called a transversal. A transversal may intersect parallel lines at an …
You come across rectangular prisms every day but you may not refer to them as rectangular prisms. This basic three-dimensional shape makes a major part of our world. Prisms are three-dimensional shapes that have flat faces on all sides and similar parallel ends. Rectangular prisms are shapes that have 6 rectangular faces. Opposite faces on …
Linear relationships describe a direct correlation between two variables, wherein a change in one variable results in a proportional change in the other, following a straight-line pattern on a graph. Unlike a nonlinear relationship, which can produce curves, bends, or other complex shapes on a graph, a linear relationship will always appear as a straight …
Decimal numbers are numbers with a point placed in them to separate some of their digits. For example, the decimal number 98.04 has a point between 8 and 0. Decimals are just a different way of expressing fractions. For example, you can express 1/4 as 0.25. This is done by dividing your fraction completely so that you …
Liters, cubic feet, gallons are just a few units of volume that we encounter every day. Volume is probably one of the most common and important measurements we use in our daily lives. It is a measurement of the space occupied by an object or substance such as gases or liquids. It can also be …
A rate is a way of comparing two things. It’s a ratio that relates two rates so that you can know how much of one goes with the other. Rates are commonly used in many situations such as in a grocery or when exchanging currency. Unit rates, also called single-unit rates, are a special type …
If you have ever dealt with triangles, then you have dealt with trigonometry. This is an area of math that studies the triangle including the angles and length relationships that define it. From plotting stars to voyaging the seas, trigonometry is all around us. The Right-angled triangle Applications in trigonometry are done with right-angled triangles. …
Triangles, squares, and circles are some of the basic shapes we encounter in our day-to-day images. They have length and width and completely enclose a space. They are referred to as two-dimensional (2D) shapes because they only have two dimensions (measurable features) i.e. length and width. Three-dimensional shapes are those that have three measurable features …
Any solid object or 3D figure has a surface area. This is the total sum that is found by adding up the area of all its sides. For example, a cylinder has 3 sides: To get the surface area, you must get the separate areas of each side and add them all up. You can …
An inverse variation is a kind of relationship where one value increases while the other one decreases. For example, if one quantity increases while the other decreases, the quantities can have an inverse relationship. Inverse variation is the opposite of direct variation, where there is a linear relationship between two variables. An inverse variation relationship …
