Transformations and Congruence in Geometry

The video tutorial covers geometric transformations, including translation, reflection, and rotation. It explains how these transformations preserve the size and shape of figures, making them congruent. The tutorial also discusses how to identify and combine transformations for complex results, providing practical examples and exercises to reinforce learning.

Which of the following transformations preserves both the shape and size of a figure?

• Stretch

• Dilation

• Translation

• Shear

What type of transformation is applied when a figure is flipped over a line?

• Reflection

• Rotation

• Translation

• Dilation

If a triangle is rotated 90 degrees clockwise, what is the direction of the rotation?

• From bottom to top

• From left to right

• From right to left

• From top to bottom

Which transformation involves turning a figure around a fixed point?

• Dilation

• Reflection

• Translation

• Rotation

What is the result of a reflection followed by a translation?

• The figure rotates

• The figure changes size

• The figure remains congruent

• The figure becomes non-congruent

In a complex transformation, which step is typically performed first?

• Translation

• Dilation

• Reflection

• Rotation

What is the term for figures that have the same shape and size?

• Equivalent

• Congruent

• Identical

• Similar

Which transformation does not preserve the size of a figure?

• Dilation

• Rotation

• Reflection

• Translation

What is the effect of a rotation on the orientation of a figure?

• Changes the size

• Changes the shape

• Changes the orientation

• No effect

Which transformation can result in non-congruent figures?

• Rotation

• Reflection

• Translation

• Dilation
