Which sequence of rigid transformations will map the preimage ΔABC onto image ΔABC?
The identity transformation.
Explain why a glide reflection is an isometry?
Because the glide reflection is a combination of two isometries, it is also an isometry.
Is a rotation an isometric?
Rotations, reflections, and translations are all isometries while a dilation isn't because it doesn't preserve distance
Which of the following is a congruence transformation?
Reflecting
What does it mean to prove that two figures are congruent using rigid motions?
Proving that two figures are congruent using rigid motions involves demonstrating that one figure can be transformed into the other through a series of translations, rotations, and reflections without changing the size or shape of the original figure. This proof relies on the principle that rigid motions preserve distance and angle measures. By showing that the corresponding parts of the two figures align perfectly after applying these transformations, it can be concluded that the figures are congruent.
Why are transformations called rigid transformations?
Transformations are called rigid because they do not change the size or shape of the object being transformed. In rigid transformations, distances between points remain the same before and after transformation, preserving the object's overall structure. This property is important in geometry and other fields where accurately transferring or repositioning objects is required.
What are not rigid motion transformations?
Dilation, shear, and rotation are not rigid motion transformations. Dilation involves changing the size of an object, shear involves stretching or skewing it, and rotation involves rotating it around a fixed point. Unlike rigid motions, these transformations may alter the shape or orientation of an object.
How can rigid transformations be used to prove congruency?
Rigid transformations, such as translations, reflections, and rotations, preserve the length, angle measures, and parallelism of geometric figures. By applying a combination of these transformations to two given figures, if the transformed figures coincide, then the original figures are congruent. This is because if two figures can be superimposed perfectly using rigid transformations, then their corresponding sides and angles have the same measures, establishing congruency.
What transformations are considered rigid?
Rigid transformations are those that do not change the shape or size of the object. They include translation (moving the object without rotating or resizing it), rotation (turning the object around a fixed point), and reflection (flipping the object over a line).
Which sequence of rigid transformations will map the preimage ΔABC onto image ΔABC?
The identity transformation.
What effects do rigid transformations have on geometric figures?
They can alter the location or orientation of the figures but do not affect their shape or size.
What is the composition of two isometries?
Preservation of Length
Which transformation or sequence of transformations can be used to show congruency?
To show congruency between two shapes, you can use a sequence of rigid transformations such as translations, reflections, rotations, or combinations of these transformations. By mapping one shape onto the other through these transformations, you can demonstrate that the corresponding sides and angles of the two shapes are congruent.
Is a composition of any two isometries always is an isometry?
Yes, that is correct.
Why reflections translations and rotation are rigid motion s?
Reflections, translations, and rotations are considered rigid motions because they preserve the size and shape of the original figure. These transformations do not distort the object in any way, maintaining the distances between points and angles within the figure. As a result, the object's properties such as perimeter, area, and angles remain unchanged after undergoing these transformations.
Explain why a glide reflection is an isometry?

Is a rotation an isometric?
