The triangles above are similiar. Determine the Scale Factor and solve for x.

• SF = 4; x = 4

• SF = 4.5; x = 5

• SF = 1/4 ; x = 4

• SF = 3.5; x = 3

Is ΔABC ~ ΔDEF? Why?

• No; Scale Factors don't match

• Yes; SF = 5

• No; SF = 5

• Yes; Not enough information

Is ΔABC ≅ ΔXYZ?

How do you know?

• No; Markings don't match

• Yes; SAS

• Yes; AAS

• Yes; ASA

Are the two triangles congruent?

• Yes; SAS

• Yes; AAS

• No; SSA doesn't work

• No; markings don't match
