GEO U3 L1-L2 Practice (Reflections and Translations)

Front

What is the term for 'sliding' a figure in geometry?

Back

Translation

Front

What is the mathematical term for the line that you reflect a shape over?

Back

Line of reflection

Front

How do you translate triangle A'B'C' to triangle ABC?

Back

(x+2, y-9)

Front

What is the line of reflection for a shape reflected over x = -3?

Back

x = -3

Front

How do you translate triangle ABC to triangle A'B'C'?

Back

(x - 2, y + 9)

Front

What is the definition of a translation in geometry?

Back

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

Front

What is the effect of a reflection on a geometric figure?

Back

A reflection creates a mirror image of the figure over a specified line.

Front

What are the coordinates of a point after a translation of (x + 3, y - 4)?

Back

(x + 3, y - 4)

Front

What is the difference between a translation and a reflection?

Back

A translation moves a figure without changing its orientation, while a reflection flips a figure over a line.

Front

If a point (2, 3) is reflected over the line y = 1, what are the coordinates of the reflected point?

Back

(2, -1)
