What set of reflections would carry triangle ABC onto itself?
To carry triangle ABC onto itself through reflections, you can use the reflections across its medians, angle bisectors, or altitudes. Specifically, reflecting across the angle bisectors of the triangle will map each vertex to the opposite side, preserving the triangle's shape. Additionally, reflecting across the perpendicular bisectors of the triangle's sides will also result in the triangle being mapped onto itself. These reflections maintain the congruence and orientation of the triangle.
Can the composite of two reflections be both a rotation and a translation?
No, the composite of two reflections cannot be both a rotation and a translation. When you perform two reflections across two lines, the result is either a rotation if the lines intersect or a translation if the lines are parallel. Thus, the outcome is distinctly one or the other, but not both simultaneously.
A figure in the coordinate plane is reflected across the line y=x+2 and then across the line y=x+4. what is the translation vector that describes the composition of the reflections Give your answer in vector format?
6
Is line reflection a direct isometry?
if there is an even number of line reflections then yes. if there is n odd number of line reflections, then no.
Which transformation will be equivalent to rotating a figure 90 counterclockwise?
An equivalent transformation to rotating a figure 90 degrees counterclockwise can be achieved by reflecting the figure across the line (y = x) and then reflecting it across the x-axis. This combination of reflections results in the same final orientation as the 90-degree counterclockwise rotation.
What are reflections that occur at changes in impedance?
Return loss refers to the reflections that occur at changes in impedance.
Where do reflections occur?
In the mirror.

Is glide reflection equivalent to two reflections across two vertical lines?
No. Glide reflection is a combination of an ordinary reflection and a slide along the line of reflection. A two reflections across two vertical lines is a translation without any reflection or rotation.
What are properties of reflections m?
Reflections in mathematics preserve the size and shape of the object being reflected. They also have the property that the reflected image is the same distance from the line of reflection as the original object. Additionally, reflections can be described by an axis of reflection, which serves as a line that the reflection occurs across.
What are multiple reflections called?
Multiple reflections are called reverberations. They occur when sound waves bounce off multiple surfaces before reaching a listener, creating a complex series of echoes that can affect the quality of the sound.
What does reversed mean in reflections?
In reflections, "reversed" means that the image appears flipped from left to right compared to the original object. Each point on the object is reflected across the mirror line to create the reversed image.
Can the composite of two reflections be both a rotation and a translation?
No, the composite of two reflections cannot be both a rotation and a translation. When you perform two reflections across two lines, the result is either a rotation if the lines intersect or a translation if the lines are parallel. Thus, the outcome is distinctly one or the other, but not both simultaneously.
How can you tell from the coordinates that two points are reflections of each other across the y axis?
The coordinates will be the same numerically but with different + and - signs.
