What is geometric reflection?
• The enlargement or reduction of an object
• The transformation of an object across a line, creating a mirror image
• The rotation of an object around a fixed point

REFLECTION
A reflection is a transformation that flips a shape or object over a line (often called the "line of reflection"), creating a mirror image. The size and shape of the object remain the same.

What is geometric dilation?
• A transformation that changes the size of a figure without changing its shape
• A transformation that rotates a figure around a fixed point
• A transformation that reflects a figure over a line

DILATION
Dilation is a transformation that changes the size of an object or shape while maintaining its shape and orientation. It can involve enlargement (making it larger) or reduction (making it smaller).

Pre-Image
the original shape or figure before any transformation (such as rotation, reflection, or dilation) is applied to it.

What is a geometric pre-image?
• A shape with equal sides and angles
• The original shape before any transformations
• A shape obtained after applying transformations

What is the "image" in geometry?
9. Slide

Image
resulting shape or figure after a transformation has been applied to the pre-image. It is the transformed version of the original shape.

What is a vector in mathematics?
• A quantity with magnitude and direction
• A shape
• A whole number

Vector
Mathematical representation of a quantity that has both magnitude (size) and direction. Vectors are often represented as arrows with a specific length and direction and are used to describe motion

13. Slide
60 seconds
Imaginary straight line used as a reference to measure or describe the position, direction, or movement of objects in space. Axes can be horizontal (x-axis), vertical (y-axis), or even diagonal depending on the context.

In geometry, what is a vertex?
• The point where two or more lines meet
• An angle greater than 90 degrees
• A three-dimensional shape

VERTEX
A point where two or more lines or edges meet. It is like a corner in a shape, where the sides or edges come together. Imagine it as the point where you can turn in different directions, like the corners of a book or the meeting point of two roads.

• Always intersect
• Never intersect
• Only intersect at right angles

Perpendicular lines are lines that:
• Intersect at a 45-degree angle
• Intersect at a 90-degree angle
• Never intersect
