Prove that if the diagonal of a parallelogram does not bisect the angles through the vertices to which the diagonal is drawn the parallelogram is not a rhombus?
Suppose that the parallelogram is a rhombus (a parallelogram with equal sides). If we draw the diagonals, isosceles triangles are formed (where the median is also an angle bisector and perpendicular to the base). Since the diagonals of a parallelogram bisect each other, and the diagonals don't bisect the vertex angles where they are drawn, then the parallelogram is not a rhombus.
How many triangles are formed by the diagonals from six vertices of a hexagon?
The three major diagonals in an ordinary hexagon do not intersect at the same point. Therefore, in such a hexagon, the diagonals form 111 triangles.
Which point in a triangle is equidistant from the vertices's of the triangle?
Not sure about vertices's. The circumcentre is equidistant from a triangle's vertices (no apostrophe).
Does a rhombus have at least have one right angle?
The vertices of a rhombus have no right angles but its diagonals intersect each other at right angles.
What shapes have diagonals bisect vertex angles?
Only a square and a rhombus will have all its diagonals bisecting vertices. In other shapes some - but not all - diagonals can bisect vertices.
Do the point at which the diagonals of a parallelogram intersect is always equidistant from the four vertices?
No because the diagonals of a parallelogram are of different lengths
The point at which the diagonal of a parallelogram intersect is equidistant from the four vertices?
sometimes
The point at which the diagonals of a parallelogram intersect is. equdistant from the four vertices?
The statement is no true.
Can a parallelogram be separated into 4 triangles?
Yes, a parallelogram can be separated into four triangles. This can be achieved by drawing two diagonals that intersect at the center of the parallelogram, dividing it into four triangular sections. Each triangle shares a vertex at the intersection point of the diagonals and the opposite vertices of the parallelogram.
How do you draw a pentagon with two outside diagonals?
To draw a pentagon with two outside diagonals, first sketch a regular pentagon by marking five equidistant points on a circle and connecting them in sequence. Next, identify any two non-adjacent vertices of the pentagon. From each of these vertices, draw straight lines connecting them to the other two non-adjacent vertices, creating the diagonals that extend outside the pentagon. Ensure that the lines are clearly defined and do not intersect with the pentagon itself.
How do you construct a parallelogram whose one side and two diagonals are given?
To construct a parallelogram with one side and two diagonals given, start by drawing the given side as one of the sides of the parallelogram. Label the endpoints of this side. Then, using a compass, draw arcs from each endpoint of the side with radii equal to the lengths of the diagonals, intersecting at two points. These intersection points will be the other two vertices of the parallelogram. Finally, connect these vertices to form the complete parallelogram.

What are the lengths of the diagonals and their point of intersection of a quadrilateral with vertices at 1 7 and 7 5 and 6 2 and 0 4?
The given vertices when plotted on the Cartesian plane forms a rectangle with diagonals of square root of 50 in lengths and they both intersect at (3.5, 4.5)
Do the diagonals of a kite intersect at 90 degree angles?
Yes, the diagonals of a kite intersect at right angles (90 degrees). In a kite, one diagonal connects the vertices of the two pairs of equal-length sides, while the other diagonal connects the vertices of the unequal angles. This unique property of kites ensures that the diagonals are perpendicular to each other.
Which theorem explains why the circumcenter is equidistant from the vertices of a triangle?
The theorem that explains why the circumcenter is equidistant from the vertices of a triangle is the Circumcenter Theorem. This theorem states that the circumcenter, which is the point where the perpendicular bisectors of a triangle intersect, is equidistant from all three vertices of the triangle. This is because the perpendicular bisectors of the sides of a triangle are equidistant from the endpoints of those sides, thus ensuring that the circumcenter maintains equal distances to each vertex.
Which shapes diagonals do not bisect its angles?
In general, the diagonals of irregular polygons do not bisect the angles at their vertices. Specifically, in shapes such as trapezoids, kites, and irregular quadrilaterals, the diagonals may intersect at angles that do not evenly split the angles of the vertices. This contrasts with regular polygons, where diagonals do bisect angles due to their symmetrical properties.
