Congruent Triangles

Triangle ABC is reflected across line AC. Are Triangle ABC and Triangle AB'C congruent?

• Yes

• No

Polygon A and B are...

• Congruent

• Not Congruent

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

After a transformation, the shape still has the same size, area, angles and line lengths.

• True

• False

This is an example of

• a reflection

• a rotation

Corresponding angles are

• matching angles between the two triangles

• matching parts of a circle

A triangle with 3 congruent sides is called:

• Equilateral

• Scalene
