What are the lengths of the diagonals in a quadrilateral when angle 95 degrees is between sides 4.3cm by 3.4cm and angle 115 degrees is between sides 3.4cm by 3.8cm?
Using the cosine formula in trigonometry the diagonals of the quadrilateral works out as 5.71cm and 6.08cm both rounded to two decimal places
Is a quadrilateral with at least one right angle and congruent diagonals a rectangle?
Yes
A quadrilateral where each angle is at a right angle?
A rectangle, or could be a square if lengths are the same.
What type of quadrilateral always has a right angle and congruent diagonals?
a rectangle yo mama
What quadrilaterals have diagonals that bisect the angels of the quadrilateral?
Rhombus and square are the only quadrilaterals whose diagonals bisect the angles of the quadrilateral. In both these quadrilaterals, the diagonals intersect at right angles, dividing each angle into two equal parts.

What quadrilateral do form diagonals a 30 angle?
Any quadrilateral other than a square or kite could have diagonals meeting at 30 degrees.
Which quadrilateral must have diagonals that are congruent and perpendicular?
The quadrilateral that must have diagonals that are congruent and perpendicular is the square. This is because its diagonals form a right angle at its center.
What quadrilateral has diagonals that dont meet at a right angle?
Why a rhombus of course.
Is an exterior angle of a quadrilateral is 90 degrees?
is an exterior angle of a quadrilateral always sometime or never 90 degrees
Is a quadrilateral with at least one right angle and congruent diagonals a rectangle?

Interior angle of a convex quadrilateral?
The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?
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)
What quadrilaterals have diagonals that bisect the angels of the quadrilateral?
Rhombus and square are the only quadrilaterals whose diagonals bisect the angles of the quadrilateral. In both these quadrilaterals, the diagonals intersect at right angles, dividing each angle into two equal parts.
What is the sum of the angle of quadrilateral?
360 degrees
