What is a rhombus Does a rhombus have a right angle?
A rhombus is a quadrilateral with four sides of equal length. It does not necessarily have a right angle. A rhombus can have all angles equal but not necessarily 90 degrees.
Is a rhombus a congruent quadrilateral?
A rhombus is a quadrilateral with 4 equal sides but no corner right angles.
How many angles triangles circles and rectangles are in a rectangular prism?
In a rectangular prism, there are 8 corners, or vertices. each corner has 3 dimensions, so there would be 3 angles per corner, for a grand total of 24 angles. There are no triangular or circular faces on a rectangular prism. There are 6 rectangular faces.
What is the name for a corner in maths?
a corner in maths is called vertices
What are corner points on a triangle?
vertices

Is a rhombus a congruent quadrilateral?
A rhombus is a quadrilateral with 4 equal sides but no corner right angles.
What are the properties of quadrilateral?
A quadrilateral is any plane figure bounded by four straight lines. If a line is drawn from one corner to the opposite corner of a quadrilateral then it is divides the quadrilateral into two triangles. As the sum of the angles of a triangle is 180° then the sum of the internal angles of a quadrilateral total 360°. Special forms of a quadrilateral are :- Parallelogram, Rhombus. Rectangle, Square, Trapezoid / Trapezium and Kite.
What are the vertices of an octagon?
A vertex is a corner where two sides meet. With flat shapes like triangles and octagons they are often called angles. An octagon has 8 vertices, and 8 sides.
Why does all quadrilaterals add up to 360 degrees?
Proof:Draw any quadrilateral. Draw a line from one corner to the opposite corner. This line is called a diagonal and quadrilaterals have two of them. Some quadrilaterals won't have both diagonals completely within the quadrilateral but they all have at least one diagonal with this property. Using this diagonal it is clear to see the quadrilateral is divided into 2 triangles and that adding up all the angles in the triangle will give you the sum of the quadrilateral. Since the angle sum of any triangle is 180 degrees and we have two triangles we have 360 degrees.Generalisation:Any polygon with n corners (called vertices) has n edges. You can take a polygon with n-1 vertices for n>=4 and stick a triangle onto one edge and you increase the angle sum by 180 degrees. So the angle sum of a polygon with n vertices is 180*(n-2) for n>=3.

Is vertices the mathematical word for corner?
No. A corner is a vertex. The plural, for corners, is vertices - not verticies as you chose to spell it.

What are two fatures of a rhombus?
Two features of a rhombus are it is a quadrilateral shape because it has 4 sides which are equal in length and it has no corner right angles but its diagonals are perpendicular.
What are corner points on a triangle?
vertices
Is there Another name for a small corner?
the answer is vertices e.g a restangle has 4 vertices
Do all quadrilaterals have at least one right angle true or false?
False because it depends on what type of a 4 sided quadrilateral it as for example a square has 4 right angles whereas rhombus has no corner right angles.
