## Unit 1 Test Review

### Use the triangle R(–7, –1), S(2, 1), and T(–5, 3)

1. Find the coordinates of R”S”T” after a translation <3,-5> followed by a reflection over the y-axis.

R”_____________ S”________________ T”_______________

2. Write one netalgebraic rule that can be used to transform any point under this composition.

3. Using the rule from question 6, find the image of the point X(4, -3) under this composition.

### The figures below are similar:

• 1. Find the scale factor from ABCDEF to LMNOPQ

• 2. Determine the value of x.

• 3. Write a similarity statement

### For questions 1 – 4, use the figure below.

• By what scale factor is quadrilateral FKXS being dilated?

2. Write an algebraic rule to describe the transformation.

3. Using your rule from question 2, find the image of point A(1, -4) under this transformation.

4. If the perimeter of FKXS is 21 units, what is the perimeter of F’K’X’S’?

5. If the area of FKXS is 5.5 units2, what is the area of F’K’X’S’?
