Geometry and Linear Functions Vocabulary

A set of vocabulary flashcards defining key geometric concepts, properties of special quadrilaterals, and fundamental linear function terms from the lecture.

Rectangle

A parallelogram in which opposite sides are equal and parallel, and all angles are equal, each measuring $90^\circ$ (for example, $m\angle M = 90^\circ$, $m\angle N = 90^\circ$, $m\angle O = 90^\circ$, and $m\angle P = 90^\circ$).

Rhombus

A parallelogram in which all sides are equal and congruent ($EF = FG = GH = EH$), and opposite sides are parallel.

Domain

The set of all possible input values of a function, which can be expressed in different representations.

Range

The set of all possible output values of a function, which can be expressed in different representations.

Slope

The rate of change of a linear function represented in graphs, equations, and tables of values.

Zero of a Linear Function

The value for which a linear function equals zero, determined from graphs, equations, or tables of values.

Parallelogram

A quadrilateral whose properties are used to find measures of angles, sides, perpendicular height, and diagonals.

Transversal

A line that intersects two or more parallel lines, creating angle pairs with determinable angle measures.

Quadrilaterals

Four-sided geometric figures classified based on formal definitions.

Parallel Lines

Lines in a plane that do not intersect, governed by specific conditions that guarantee parallelism when cut by a transversal.

Perpendicular Lines

Lines that intersect to form right angles, governed by specific conditions that guarantee perpendicularity.

Function

A specific relation identified based on formal definitions of relations and functions.
