SPIRAL 2-GEOMETRY

Figure ABCD ≅ WXYZ. If AB || DC , what statement must be TRUE?

• AD || DC

• WX || ZY

• BC || AD

• WZ || BC

Imagine figure ABCD is translated two units to the right and rotated 90° counter-clockwise about the origin to form figure A'B'C'D'. Which statement is TRUE about the two figures?

• The figures are congruent.

• The figures are similar but not congruent.

• The figures are neither similar nor congruent.

• It is impossible to determine similarity or congruence without seeing a visual representation of the sequence of transformations.

Which coordinate represents the image of A(4,5) after a translation of (x,y) → (x + 3,y – 5)?

Choose the best description of ∠ABC and ∠RST.

• ∠ABC is similar to ∠RST because they meet Angle-Angle Criterion

• ∠ABC is similar to ∠RST because they meet Side-Angle-Side Criterion

• ∠ABC is congruent to ∠RST because they meet Side-Side-Side Criterion

• ∠ABC is not similar to ∠RST because they do not meet any criterion for angles

Using the figure below, find the m∠SRT.

• 35°

• 180°

• 145°

• 105°
