Also called dimension, it is the number of independent parameters in mathematics.
When two lines are cut by a third line, the two angles on the same side of the transversal and inside the two lines are called consecutive interior angles. When the two lines are parallel, consecutive interior angles are supplementary (they add up to 180°). Conversely, if consecutive interior angles are supplementary, then the two lines are parallel.
A satellite refers to a natural celestial body that orbits a planet and moves periodically along a closed orbit. Artificial satellites can generally also be called satellites.
Two lines a and b are cut by a third line c. The angles that are on the same side of the cutting line c and on the same side of the two lines a and b are called corresponding angles. When lines a and b are cut by a third line c, 'three lines and eight angles' appear, which include 4 pairs of corresponding angles, 2 pairs of alternate interior angles, and 2 pairs of same-side interior angles.
Place value, simply put, means that a number represents different amounts depending on where it stands in a row. For example, the number "2" is just two ones in the ones place, but two hundreds in the hundreds place. This is the basic principle in math of using digits and place values to represent numbers, and it's the rule behind the decimal system used worldwide and the binary system used in computers.
Probability is a branch of math that studies the patterns of random events, showing the chance of something happening with a number between 0 and 1.
It's a small cube used for playing games or deciding wins and losses, with each side showing 1, 2, 3, 4, 5, or 6 dots.
An irrational number is a real number that can't be expressed as an integer or a fraction. If you write an irrational number in decimal form, it will have an infinite number of digits after the decimal point with no repeating pattern, so it's also called a non-repeating infinite decimal.
A convex polygon is a polygon where all the interior angles are less than 180 degrees, with no 'indentations,' and any line connecting two vertices stays inside the shape.
