Congruent Triangles

Mr. Ortiz used similar triangles to make a design. Which statement about the triangles in the design must be true?

• The are the same size and shape.

• They are the same size but different shapes.

• They have corresponding angles that are congruent.

• They have corresponding sides that are congruent.

What does congruent mean?

• Same shape, different size

• Not same shape, or size

• Same size, same shape

The pair of figures is similar. Find the missing side.

• x = 12

• x = 3
