Naming Geometric Figures Flashcards

Naming Geometric Figures

• Line: A straight path that extends infinitely in both directions without curves.
• Line Segment: A portion of a line bounded by two distinct endpoints.
• Ray: A line that begins at a specific point and extends infinitely in one direction.
• Angle: Formed by two rays or lines that diverge from a common endpoint known as the vertex.
• Parallel Lines: Two lines in a plane that will never intersect or meet, no matter how far extended.
• Perpendicular Lines: Lines that intersect to form a right angle (90°), creating distinct angles.
• Perpendicular Bisector: A line that divides a line segment into two equal parts while intersecting it at a right angle.
• Angle Bisector: A line that divides an angle into two equal angles.
• Translation: A geometric transformation that shifts an object a specified distance without changing its shape, size, or orientation.
• Reflection: A transformation that produces a mirror image of a geometric figure across a designated line called the axis of reflection.
• Rotation: A transformation that turns a figure around a fixed point, maintaining at least one point stationary.
• Isometry: A transformation that preserves distances between points, effectively maintaining the size and shape of the figure.
• Rigid Transformations: Movements that do not change the shape or size of a figure, comprising rotations, reflections, and translations.
• Congruent: Describes two or more shapes that are identical in both shape and size.
• Commutative: Refers to the property that the order of operations does not affect the outcome, such as in multiplication (a × b = b × a).
• Preserve: To maintain the existence or continuity of something, keeping it unchanged.
• Vertex: The point where two or more lines or segments meet, generally considered a corner of a shape.
• Composite Transformations: The application of two or more transformations in sequence to achieve a final result.
