which is true?

• AB≅XY
• AB≅YX
• AB≅XZ
• BC≅CB

∠U = ≅

• ∠F
• ∠G
• ∠E

Which of the following statements is not true if  ΔJKL ≅ ΔMNO?

• ∠J ≅∠M
• ∠N ≅ ∠K

The triangles are congruent. Which of the following statements must be true?

• ∠A ≅ ∠D
• ∠B ≅ ∠E
• AB ≅ DE
• BC ≅ FD

Are the two figures similar?

• yes
• no

When talking about figures on a coordinate plane, what does "congruent" mean?

• Same shape, same size
• Same shape, size changes
• Different shape, different size
• Same shape, different size

Tell whether the two figures are similar. Explain your reasoning.

• Yes, similar because they are the same shape and side lengths are proportional.
• No, not similar because they are the same shape, but side lengths are not proportional.
• Yes, same shape
• No, different sizes
