Congruent - the same

Two shapes are congruent when you can turn, flip, and or slide one so it fits exactly on top of the other (identical size and shape) - the same.

A congruent is 2 shapes that fit onto of the other by flipping, sliding or turning over the other

The con grew ants (congruent), but they all looked exactly the same.

 

Example 1

These shapes have been flipped but are exactly the same so they are congruent 

If these arrows were placed on top of each other and were facing the same way, they would be exactly the same and so they are congruent.

 

Example 2

These shapes have been slid but are exactly the same so they are congruent

These two triangles are congruent because if you slide them over each other, they would fit perfectly.

 

Example 3

These shapes have been rotated but are exactly the same so they are congruent

Although one of these rectangles is on its side, they are still congruent. If you rotate one, it would fit perfectly over the other.

 

Example 4

These complex shapes are the same so they are congruent

These odd shapes fit perfectly over one another, and so they are congruent shapes.
