Congruence and similarity are important ideas in geometry!

Congruence

• What it Means: Two shapes are congruent if they are exactly the same in both shape and size.
• How to Get There: You can make shapes congruent by moving them around, turning them, or flipping them.
• Example: Think of two triangles. They are congruent if you can change one into the other without making it bigger or smaller.

Similarity

• What it Means: Two shapes are similar if they look the same but are different sizes.
• How to Get There: You can make shapes similar by resizing them, along with moving, turning, or flipping.
• Example: A small triangle and a big triangle that have the same angles are similar to each other.

Remember, congruent shapes are like twins—they look exactly alike! Similar shapes are more like siblings—they share some features but are not the same size.
