No, a rhombus does not always have congruent diagonals. A rhombus is a quadrilateral that has four equal sides, but the diagonals may or may not be congruent. For the diagonals to be congruent, the angles of the rhombus must be of equal measure, resulting in the four angles being exactly 90 degrees each.
If the angles are not all 90 degrees, then the diagonals will not be congruent. Additionally, if the four sides are not completely equal in length, then the diagonals will also be of different lengths and the rhombus will not have congruent diagonals.

What can a rhombus be but not always?
A rhombus can be many things, but it is not always a parallelogram. A rhombus is a type of parallelogram with four sides that are all equal in length and opposite angles that are equal in measure. All the sides of a rhombus are also parallel to each other.
A rhombus has many unique properties that set it apart from other polygons and these properties can cause it to be used for different applications. For example, a rhombus can be used in engineering to construct structural elements, such as beams, trusses, and frames.
In addition, rhombi can be employed in architecture as a decorative element or window frame. They can also be used in art, as they can be tiled and arranged together to form intricate patterns.
But a rhombus doesn’t need to be limited to the engineering and art realms. It can also be used in mathematics. For instance, a rhombus can be used to create geometric solids, like cubes and cylinders.
Furthermore, it can be used to illustrate properties of shapes and angles, such as equal side lengths and equal angle measure.
In conclusion, a rhombus can be many things, but it is not always a parallelogram. It can be used in engineering, architecture, art, and mathematics, amongst other fields.
What are the 4 properties of a rhombus?
The 4 properties of a rhombus are:
1. All sides of a rhombus are equal in length, meaning it is a four-sided shape with four equal-length sides.
2. All angles of a rhombus are equal, meaning that any two opposing angles of the rhombus are equal in size.
3. A rhombus is a type of parallelogram, meaning that two pairs of opposite sides are parallel to each other.
4. A rhombus is a symmetrical shape – any line of symmetry through the centre of the rhombus will divide it into two exactly equal halves.
What shapes have all sides congruent?
A shape that has all sides congruent is known as a regular polygon. This type of shape has sides that are equal in length and angles that are equal in size. Examples of regular polygons include squares, rectangles, pentagons, hexagons, octagons, and dodecagons.
Depending on the number of sides, regular polygons are also referred to as equilateral polygons. Regular polygons are the only shapes with all sides congruent and all angles congruent. Other types of shapes, such as circles, ellipses, and triangles, do not have all sides congruent.
Are the diagonals of a rhombus congruent and perpendicular?
Yes, the diagonals of a rhombus are congruent and perpendicular. The diagonals of a rhombus intersect at the midpoint of the opposite sides, forming two pairs of congruent triangle (isosceles triangle) and each pair being in opposition to each other.
This establishes that the two pairs are perpendicular to each other and makes the diagonals of a rhombus both congruent and perpendicular. The diagonals bisect each other at 90 degree angles showing that they are indeed perpendicular.
What diagonals are perpendicular and congruent?
Diagonals that are perpendicular and congruent are two lines drawn from opposite corners of a rectangle or parallelogram to the opposite corners. These diagonals will intersect each other at the exact center of the shape and create four equal triangles.
They will also be perpendicularly opposite in direction and will have the same length. Both diagonals are equal and perpendicular, so they are said to be perpendicular and congruent.
How do you prove that a rhombus diagonals are perpendicular?
To prove that the diagonals of a rhombus are perpendicular, you can use the properties of a rhombus. A rhombus is a quadrilateral with four equal sides and the opposite sides are parallel. Its diagonals intersect at their midpoints and, when extended, bisect each other.
Additionally, the length of the diagonals of a rhombus are always equal. Therefore, to prove that the diagonals of a rhombus are perpendicular, you can use the distance formula to calculate the lengths of the diagonals and show that they are equal.
You can also use the properties of parallelograms, since a rhombus is a special type of parallelogram, to show that the diagonals must be perpendicular since the opposite sides of a parallelogram are both parallel and equal.
Finally, you can use the fact that the angles of a rhombus are equal, and then the angles of the diagonals must be equal as well, meaning they must form a 90 degree angle in order to be perpendicular.
What are both congruent and perpendicular?
Congruent and perpendicular are geometric terms used to describe two figures that have the same size and shape and meet at a 90 degree angle, respectively. Congruent figures have the same height and width, and are found when two lines, segments, or objects have the same length.
Perpendicular lines are two lines that form a 90 degree angle when they intersect. Two lines can be perpendicular to each other, or a line can be perpendicular to a plane or a curve. In the two-dimensional Euclidean plane, two lines are perpendicular if the slope of one line is the negative reciprocal of the other line.
If a third line is drawn through the point of intersection of the two perpendicular lines, they form a right angle.
Are diagonals congruent in a rhombus?
Yes, diagonals are congruent (of equal length) in a rhombus. A rhombus is a quadrilateral whose sides are all equal in length, so when the diagonals are drawn to bisect each other, they have to be the same length.
In addition to being congruent, the diagonals of a rhombus also intersect at 90-degree angles and bisect each other.
Which diagonals are always equal?
The diagonals of a square or any other regular polygon (such as a pentagon or hexagon) are always equal. This is because all sides of the polygon are equal, and the same distance is maintained from the center to the outer points in each diagonal.
This means that the diagonals create two equal triangles, and as the sides are equal, so too are the diagonals. This is also true of parallelograms and rhombuses, as they also have opposite sides which are parallel and of the same length.
