Geometry - Semester 1 Exam

Front

What is the result of translating the point (5, 2) using the translation (x + 2, y - 7)?

Back

(7, -5)

Front

How do you translate triangle ABC to triangle A'B'C' using the translation (x-2, y+9)?

Back

The translation moves each point of triangle ABC 2 units left and 9 units up.

Front

What is the new location of the point (-5, 2) after reflecting it over the y-axis?

Back

(5, 2)

Front

What are translations, reflections, and rotations collectively known as?

Back

Transformations

Front

What property is illustrated by the statement m = m?

Back

Reflexive property

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 definition of reflection in geometry?

Back

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

Front

What is the definition of rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

If a point (x, y) is translated by (x + a, y + b), what are the new coordinates?

Back

(x + a, y + b)

Front

What is the formula for reflecting a point (x, y) over the x-axis?

Back

(x, -y)
