Alternate interior angles are the angles made on the opposite sides of the transversal. In other words, when two parallel lines are crossed by a transversal, eight angles are formed. Among these, the angles that lie on the inner side of the parallel lines but on the different sides of the transversal are known as … Read more
The three most common ways to change a conditional statement are by taking its inverse, its converse statement, or its contrapositive. In each case, either the hypothesis or the conclusion swap places, or a statement is replaced by its negation. The Inverse Statement A conditional statement is reversed by replacing the hypothesis and the conclusion … Read more
Rounding Decimals: Utilizing a calculator often gives a long string of digits. For instance, 1 ÷ 3 might give .333333333. But very often, for practical goals, this level of accuracy is too precise to be useful. You try measuring .33333333 meters! Decimal numbers can be rounded quite like whole numbers. For example, 0.33333333 is nearer … Read more
Relationships one to one function refer to relationships between any two items in which one can only belong to one other item. In a mathematical sense, these relationships are known as one-to-one functions, in which there are equal numbers of items or in which one item is paired with only one other item. The name … Read more
There are terms that describe place value for decimals in the same way that those terms describe place value for whole numbers, such as tenths, hundredths, thousandths, ten thousandths, hundred thousandths, millionths, etc. Beginning with the first numeral after the decimal point, these terms are used from left to right. In the number 0.1234, there … Read more
The axis of symmetry is a straight line that divides an object into two identical parts, thus creating one part as a mirror image of another. Folded along the axis of symmetry, the two parts become superimposed. In terms of symmetry, the mirror line is the straight line. The horizontal, vertical, or slanting line can … Read more
Parabolas are graphs of quadratic functions in mathematics. A parabola is a projective curve of a circle, according to Pascal. Galileo described a path called a parabolic path that is followed by projectiles falling under uniform gravity. In most cases, physical motions of bodies follow a curvilinear path in the shape of a parabola. Parabolas … Read more
