Transformations and Congruence in Geometry

The video covers various lessons on transformations, including moving shapes in a plane, naming transformations, applying transformations on a grid, and using coordinates. It also discusses sequences of transformations and describes transformations in terms of congruence and angles.

What transformation occurs when a shape moves vertically from one frame to the next?

• Translation

• Reflection

• Rotation

• Scaling

Which pair of cards shows a shape and its image after a reflection?

• Cards 4 and 5

• Cards 1 and 4

• Cards 3 and 5

• Cards 2 and 6

What is the result of a 90-degree clockwise rotation of a triangle on a grid?

• The triangle flips over the x-axis

• The triangle moves to the left

• The triangle rotates to a new position

• The triangle remains unchanged

What happens to a shape when it is reflected over a line?

• It rotates around the line

• It moves parallel to the line

• It scales up in size

• It flips over the line like a mirror image

Which transformation involves turning a shape around a fixed point?

• Rotation

• Reflection

• Dilation

• Translation

What is the result of a 180-degree rotation of a shape?

• The shape moves to the right

• The shape remains unchanged

• The shape flips upside down

• The shape rotates to a new position

What is the effect of a translation on a shape?

• It rotates the shape around a point

• It moves the shape without rotating or flipping it

• It changes the shape's size

• It flips the shape over a line

How can you describe a sequence of transformations that takes polygon P to polygon Q?

• A series of reflections

• A single translation

• A scaling transformation

• A combination of translations, rotations, and reflections

What is a key characteristic of congruent polygons?

• They have different angles but the same side lengths

• They are always identical in size and shape

• They can be transformed into each other using rigid transformations

• They have the same area but different shapes

How can you determine if two shapes are congruent?

• By applying a series of rigid transformations

• By comparing their areas

• By checking if they have the same perimeter

• By using a ruler to measure their sides
