• Reflect across the x-axis and then reflect across the y-axis.

• Translate up and then rotate 90 degrees about the origin.

∆ABC≅∆XYZ

which is true?

• The corresponding angles and sides of the two triangles are congruent

• The corresponding sides are congruent, but they have different angles

• The corresponding angles of the triangles are congruent, but not their sides.

• The two triangles are completely different sizes and shapes.

Which statement proves that these triangles are similar?

• Triangle ABC is dilated with a scale factor of 2, which means its image is similar.
