# Are two figures congruent if they have the same shape?

## Are two figures congruent if they have the same shape?

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

## When shapes are congruent what is the same?

Two shapes that are the same size and the same shape are congruent. Shapes A, B, E and G are congruent. They are identical in size and shape.

What do you call a polygon with the same size and shape?

Definition: Polygons are congruent when they have the same number of sides, and all corresponding sides and interior angles are congruent. The polygons will have the same shape and size, but one may be a rotated, or be the mirror image of the other.

What is a congruent rectangle?

Opposite sides of a rectangle are the same length (congruent). The angles of a rectangle are all congruent (the same size and measure.) Remember that a 90 degree angle is called a “right angle.” So, a rectangle has four right angles. Opposite angles of a rectangle are congruent.

### Are two figures that have the same size and shape similar?

Congruent. Two figures are congruent if they have the same shape and size. Two angles are congruent if they have the same measure. Two figures are similar if they have the same shape but not necessarily the same size.

### What does it mean for 2 figures to be congruent?

Congruent figures are geometric figures that have the same shape and size. If the figures are polygons, then they are congruent if all the corresponding sides and corresponding angles are congruent. Consider the polygon shown.

What is difference between similar and congruent?

Congruent is the term used for the figures or shapes that are identical to each other in terms of shape and size whereas similar is the term that refers to the figures that look alike but do not have equal dimensions.

How are similarity and congruence alike?

Congruence essentially means that two figures or objects are of the same shape and size. Similarity means that two figures or objects are of the same shape, though usually not of the same size. Two circles will always be similar, for example, because by definition they have the same shape.

## What is congruent in polygon?

Two polygons are congruent if their corresponding sides and angles are congruent. Note: Two sides are congruent if they have the same length and angles are congruent if they have the same measure. They also have to have the same number of sides. We can think of congruent polygons as coming from the same stamp.

## What do you call a polygon that has the same measure or congruent sides and angle?

A regular polygon has congruent angles and congruent sides. Any polygon can be a regular polygon. Look at the regular polygons below.

What shape is congruent to a rectangle?

If two figures have the same shape and the same size, then they are said to be congruent figures. For example, rectangle ABCD and rectangle PQRS are congruent rectangles as they have the same shape and the same size. Side AB and side PQ are in the same relative position in each of the figures.

Do congruent rectangles have the same perimeter?

For these two rectangles to be congruent, they must have the same proportions which means that the ratio of a/b = A/B. A rectangle that is skinnier or narrower than the first rectangle: it can have sides with the same perimeter length, but it is not congruent since it is different proportionally.

### What are examples of congruent figures?

If two figures have the same shape and the same size, then they are said to be congruent figures. For example, rectangle ABCD and rectangle PQRS are congruent rectangles as they have the same shape and the same size. Side AB and side PQ are in the same relative position in each of the figures.

### What are some examples of congruent shapes?

Congruent If one shape can be rotated, reflected or translated to fit exactly onto another shape, then the shapes are said to be congruent. If we enlarge one shape to make it bigger or smaller, then the shapes are said to be similar. Some examples of similar shapes are: different size circles, an A4 and an A5 piece of paper.

What is the definition of congruent figures?

The origin of the word “congruent” is from the Latin to “agree” or “to meet together”. Intuitively, congruent figures are the same size and shape. It is possible to turn, flip and/or slide one figure so it will fit exactly on the other figure. The areas of congruent figures are equal.

What is an example of a congruent shape?

Congruent Shapes Examples Think of all the pawns on a chessboard. To summarize, congruent figures are identical in size and shape; the side lengths and angles are the same. They can be rotated, reflected, or translated, and still be congruent.
