What is the rule for the reflection?

What is the rule for the reflection?

To perform a geometry reflection, a line of reflection is needed; the resulting orientation of the two figures are opposite. Corresponding parts of the figures are the same distance from the line of reflection. Ordered pair rules reflect over the x-axis: (x, -y), y-axis: (-x, y), line y=x: (y, x).

Which statements must be true about the image of Δmnp after a reflection across line eg select three options?

The image will be congruent to ΔMNP. The orientation of the image will be the same as the orientation of ΔMNP. will be perpendicular to the line segments connecting the corresponding vertices. The line segments connecting the corresponding vertices will all be congruent to each other.

What are the four most common lines of reflection select all that apply?

By examining the coordinates of the reflected image, you can determine the line of reflection. The most common lines of reflection are the x-axis, the y-axis, or the lines y = x or y = −x. Notice that the notation tells you exactly how each (x,y) point changes as a result of the transformation.

What is the length of segment QV quizlet?

In the diagram, the length of segment QV is 15 units.

How do you reflect a point across a line?

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

What is the rule for the reflection RY axis X Y → X Y?

A reflection of a point over the x -axis is shown. The rule for a reflection over the x -axis is (x,y)→(x,−y) .

Which rule describes the composition of transformations that maps pre image PQRS to image Pqrs?

Which rule describes the composition of transformations that maps figure PQRS to figure P”Q”R”S”? The rule r y-axis • RO, 90° (x, y).

What is reflection image in geometry?

A reflection is a transformation representing a flip of a figure. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line. The fixed line is called the line of reflection.

How do you draw an image of a figure under a reflection?

the image of a figure under a reflection? Possible answer: To draw the image of a figure under a refletion across line ℓ, choose a vertex of the figure, vertex A. Draw a segment with an endpoint at vertex A so that the segment is perpendicular to line ℓ and is bisected by line ℓ.
