Geometry Unit 4 Review

Front

What is the algebraic rule for translating a point (x,y) if (9,-5) is translated to (5,0)?

Back

(x-4,y+5)

Front

What are the two transformations that describe the change from Figure 1 to Figure 2 and then Figure 2 to Figure 3 if both are reflections?

Back

Reflection, reflection

Front

If rhombus ABCD has vertices A(2,2), B(6,4), C(8,8), and D(4,6), and A' is at (-2,10), what are the coordinates of C'?

Back

(4,16)

Front

What is rotational symmetry?

Back

A figure has rotational symmetry if it can be rotated around a center point and still look the same at certain angles.

Front

What is reflectional symmetry?

Back

A figure has reflectional symmetry if it can be divided into two identical halves that are mirror images of each other.

Front

How do you determine the coordinates of a translated point?

Back

Subtract or add the translation values to the original coordinates.

Front

What is the difference between rotation and reflection in transformations?

Back

Rotation turns a figure around a point, while reflection flips it over a line.

Front

What is the formula for the distance between two points (x1,y1) and (x2,y2)?

Back

Distance = √((x2-x1)² + (y2-y1)²)
