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
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 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).
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?
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
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
Explain what is the Axis...
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
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.
In geometry, parallel lines are lines that:
- 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
