Transformations and Congruent Similar Triangles

When one shape can become another using only Turns, Flips and/or Slides, then the two shapes are

• congruent

• similar

Parts that match between two congruent triangles are called

• congruent shapes

• corresponding parts

Corresponding angles are

• matching angles between the two triangles

• matching parts of a circle

This is an example of

• a reflection

• a rotation

This is an example of a

• rotation

• translation

This is an example of a

• translation

• rotation

Reflection means

• turn

• flip

Rotation means

• to slide

• to turn

Are these triangles similar?

• Yes

• No

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