Transformations Unit Test 2024

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a shape the same distance in a specified direction.

Front

How do you perform a translation on a point (x,y) by (x+3, y-2)?

Back

You add 3 to the x-coordinate and subtract 2 from the y-coordinate.

Front

What is the result of translating point A(2,1) by (3,-2)?

Back

Point A' will be at (5,-1).

Front

What does it mean to rotate a figure 90 degrees clockwise?

Back

It means to turn the figure 90 degrees in the direction of the clock hands.

Front

If a triangle is rotated 180 degrees, what happens to its orientation?

Back

The triangle will be upside down compared to its original position.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a shape over a line, creating a mirror image.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a shape is flipped to create its reflection.

Front

What is the effect of reflecting a point on the line of reflection?

Back

The point remains unchanged if it lies on the line of reflection.

Front

What is the sequence of transformations?

Back

A sequence of transformations is a series of operations (like translation, rotation, reflection) applied to a shape.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a shape is rotated.
