Exploring Rigid Transformations Vocabulary

The video introduces math transformations, comparing them to video game sprites. It covers rigid transformations: translation, reflection, and rotation, explaining how they maintain size and shape. The video also discusses using coordinates to describe shapes and introduces polygons, highlighting regular and irregular types. It concludes with a mention of additional resources.

What type of transformation involves sliding an object either horizontally or vertically?

• Rotation

• Reflection

• Translation

• Scaling

What does a translation transformation do to a shape?

• Flips it over an axis

• Moves it to a new position without rotating

• Changes its size

• Rotates it around a central point

What is the result of a reflection transformation?

• The object moves along a line.

• The object rotates around a point.

• The object is flipped over a line.

• The object increases in size.

Which transformation does not alter the size or shape of an object?

• Dilation

• Translation

• Shearing

• Rigid transformation

What does it mean if two shapes are congruent?

• They have the same shape and size.

• They have different sizes.

• They are mirror images.

• They are both polygons.

How do you find the coordinates of a point on a graph?

• Measure the distance from the origin.

• Count the grid lines along the x-axis and y-axis.

• Use a ruler to measure the centimeters.

• Estimate the location visually.

Which axis is horizontal in a coordinate system?

• y-axis

• z-axis

• x-axis

• None, both axes are vertical.

Which of the following is true about the coordinates (7, 9)?

• It is 9 units down and 7 units to the left.

• It is 7 units down and 9 units to the left.

• It is 7 units up and 9 units to the right.

• It is 9 units up and 7 units to the right.

What distinguishes a regular polygon from an irregular polygon?

• Irregular polygons are always convex.

• Irregular polygons have all sides of equal length.

• Regular polygons have all sides of equal length.

• Regular polygons have sides of varying lengths.

What is a concave shape?

• A shape that is completely flat.

• A shape with all points extending outward.

• A shape with no angles.

• A shape with at least one inward-pointing angle.
