In mathematics, congruence refers to figures or shapes that have the same size and shape, regardless of their position. Congruence is a fundamental concept used in geometry, algebra, and trigonometry.

In this article, we will discuss into 10 examples of congruent figures in mathematics, showcasing their importance in mathematical reasoning and problem-solving.

## Examples of Congruent Figures

### 1: Congruent Triangles

Congruent triangles have corresponding sides and angles that are equal. When two triangles are congruent, they are essentially the same in terms of size and shape, even if they are oriented differently.

### 2: Congruent Rectangles

Rectangles with equal side lengths and right angles are congruent. They can be of different sizes but still maintain their congruence if their side lengths and angles match.

### 3: Congruent Circles

Circles with the same radius are congruent. The center of the circles may vary, but their size and shape remain identical.

Quadrilaterals with matching side lengths and angles are congruent. They may vary in orientation or position, but their congruence persists.

### 5: Congruent Polygons

Polygons with equal side lengths and angles are congruent. These polygons can have different numbers of sides but maintain congruence if their corresponding sides and angles are equal.

### 6: Congruent Line Segments

Line segments with identical lengths are congruent. These segments can be positioned differently but remain congruent as long as their lengths are equal.

### 7: Congruent Angles

Angles with the same measure are congruent. Regardless of their orientation or position, congruent angles have equal measures.

### 8: Congruent Congruence Transformations

Congruence transformations, such as rotations, reflections, and translations, can transform one figure into another while preserving their congruence. The figures are essentially the same in size and shape.

### 9: Congruent Vectors

In vector mathematics, vectors with the same magnitude and direction are congruent. These vectors represent the same displacement or movement, even if they start from different points.

### 10: Congruent Geometric Patterns

Geometric patterns that repeat identical shapes at regular intervals are composed of congruent elements. These patterns are often used in tessellations and mosaics.

Congruent figures in mathematics play important role in various mathematical concepts and problem-solving.
