Transformations and Congruence in Geometry

The video tutorial by Mr. Weaver covers 8th grade geometry, focusing on congruence and transformations. It explains how transformations like translations, reflections, and rotations preserve the shape and size of figures, making them congruent. The tutorial demonstrates how to use sequences of transformations to determine congruence between figures, using examples of triangles and other shapes. It also guides on identifying transformations by analyzing the order and orientation of vertices. The video includes practical examples and exercises to reinforce understanding.

Which of the following transformations does NOT change the size or shape of a figure?

• Dilation

• Translation

• Reflection

• Rotation

What is the result called when multiple transformations are applied to a figure?

• Single Transformation

• Transformation Sequence

• Transformation Composition

• Transformation Chain

What is the first step in determining if two figures are congruent using transformations?

• Check if they are the same size

• Measure the angles

• Apply a dilation

• Identify a sequence of transformations

To determine if two triangles are congruent, which sequence of transformations can be used?

• Translation, Rotation, Dilation

• Reflection, Dilation, Rotation

• Rotation, Reflection, Translation

• Translation, Dilation, Reflection

When a figure is rotated 90 degrees clockwise, what happens to its orientation?

• It remains the same

• It is reversed

• It changes direction

• It becomes larger

If a triangle is reflected across the y-axis and then translated up, what can be said about its congruence?

• It is not congruent to the original

• It is congruent to the original

• It is larger than the original

• It is smaller than the original

How can you determine the center of rotation for a figure?

• By checking the size of the figure

• By measuring the angles

• By identifying a point that remains stationary

• By finding the midpoint of the figure

Which transformation involves reversing the orientation of a figure?

• Dilation

• Reflection

• Rotation

• Translation

What is a key indicator that a reflection has occurred in a transformation?

• The figure is smaller

• The orientation is reversed

• The figure is translated

• The figure is larger

In a multiple-choice problem involving transformations, what is a useful strategy?

• Choose the longest option

• Check each option to see which works

• Guess the answer

• Select the first option
