2.1 Congruent and Similarity
**Congruent**
Figures which have the same form and are exactly the same size are called congruent. You could even say that they are copies of each other.
Rectangle A is congruent to rectangle B.
There measurements are identical: 5 cm x 3 cm.
Similarity
Figures which have the same form but that don’t have the same size are called similar. You can say that they have the same form and the same proportions.
In every rectangle, the length is twice as long as the width. The relationship between length and width in the rectangles is the same.
The rectangles A, B and C are similar. |
