Quadrilateral formed by connecting the midpoints of consecutive sides?
A parallelogram with sides whose lengths are half the diagonals of the original quadrilateral.
Can a kite have four congruent diagonals?
No because a kite is a 4 sided quadrilateral with two diagonals of different lengths that intersect each other at right angles.
How do you measure quadrilaterals with a protractor?
A quadrilateral has four sides with lengths, two diagonals with lengths, four inside angles, four outside angles, and an area. The angles are the only things you can measure with a protractor.
What is a kite dealing with geometry?
A kite is a quadrilateral that is named thus because of it's kite-like appearance. It has two pairs of sides with equal lengths that are adjacent and congruent. The diagonals of a kite intersect at ninety degrees. See the 'related link' for a picture.
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)
Quadrilateral formed by connecting the midpoints of consecutive sides?
A parallelogram with sides whose lengths are half the diagonals of the original quadrilateral.
The quadrilateral above has four sides whose lengths are represented by A B C and D If you wanted to calculate the area of the quadrilateral which of the lengths must you know to make the calculation?
diagonals
Can a kite have four congruent diagonals?
No because a kite is a 4 sided quadrilateral with two diagonals of different lengths that intersect each other at right angles.
Which parallelograms have congruent diagonals?
Only rectangles (squares included) have congruent diagonals, because all their angles are congruent (90 degrees). If you have angles larger or smaller than 90 degrees it makes the diagonals different lengths.
How do you find the length of the diagonals of an irregular quadrilateral?
You would have to consider a triangle formed by one diagonal and two sides of the quadrilateral. If you know the lengths of these sides, and the measure of the angle between them, you can use the cosine law to find the diagonal. c2 = a2 + b2 -2ab(cosC)
How do you measure quadrilaterals with a protractor?
A quadrilateral has four sides with lengths, two diagonals with lengths, four inside angles, four outside angles, and an area. The angles are the only things you can measure with a protractor.
A quadrilateral with 2 pairs of parallel sides the lengths of which are not equal?
A quadrilateral as described is a parallelogram. If the angles between the two sets of parallel lines are 90 degrees, the shape is a rectangle, a special form of 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?

What are the lengths of the diagonals of the quadrilateral abcd when ab is 4.3 cm bc is 3.4 cm cd is 3.8 cm angle abc is 95 degrees and angle bcd is 115 degrees?
If you mean quadrilateral ABCD then by using the cosine rule diagonal AC equals 5.71 cm and diagonal BD equals 6.08 cm both rounded to two decimal places.
If the diagonals of the rhombus are in the ratio 3 to 4 and the perimeter of the rhombus is 40 cm what are the lengths of the diagonals?
The lengths of the diagonals work out as 12 cm and 16 cm
How do you find the measures of a rhombus with two diagonals?
That will depend on the lengths of the diagonals of the rhombus which are of different lengths and intersect each other at right angles but knowing the lengths of the diagonals of the rhombus it is then possible to work out its perimeter and area.
