Coordinates: (-1, 4) (3, 7) (5, 2) (-1, 4)
When plotted on the Cartesian plane its diagonals of 2 times square root of 10 and 8 Times Square root of 10 will intersect each other at right angles.
Area of the quadrilateral: 0.5 times the product of its diagonals = 80 square units

What is the area of the quadrilateral ABCD whose vertices are at -1 4 and 3 7 and 5 2 and -5 -17 giving the reason for your answer?
When the given vertices are plotted and joined together on the Cartesian plane they will form a 4 sided quadrilateral whose diagonals intercept each other at right angles and so multiplying the lengths of the diagonals divided by two will produce an area of 80 square units.
What is a quadrilateral with 1 right angle 1 obtuse angle and 2 acute angles?
It is just an irregular quadrilateral.
Do irregular quadrilateral have 1 obtuse angles?
No, they do not.
How many sides do 2 pentagons and 1 quadrilateral have altogether?
A pentagon has fives sides, and a quadrilateral has four. So 2 pentagons and 1 quadrilateral have 2*5 + 4 = 10 + 4 = 14 sides altogether.
Can you draw a quadrilateral with 1 angle?
No because a quadrilateral has four interior angles that add up to 360 degrees.
How many faces does Quadrilateral have?
A quadrilateral has 4 sides and 1 face which is its surface area.
What is the area of the quadrilateral ABCD whose vertices are at -1 4 and 3 7 and 5 2 and -5 -17 giving the reason for your answer?
When the given vertices are plotted and joined together on the Cartesian plane they will form a 4 sided quadrilateral whose diagonals intercept each other at right angles and so multiplying the lengths of the diagonals divided by two will produce an area of 80 square units.
How do you find the area of a quaderlateral?
Draw a line from one corner of the quadrilateral to the opposite one and calculate the areas of the two triangles created using the formula for the area of a triangle 1/2 B*H (1/2 Base " Height). To do this see the graphic in the related links. Add the areas of the two triangles together to get the total area of the quadrilateral
What is the 1 factor that makes a quadrilateral a trapezoid?
A trapezoid is a special case of a quadrilateral which has 1 pair of parallel sides.
What is a quadrilateral with 1 right angle 1 obtuse angle and 2 acute angles?
It is just an irregular quadrilateral.
What is the area of 15cm 3cm 7cm and 1.5cm?
Too many dimensions have been given to work out an answer.
How many faces a quadrilateral have?
1
Can a quadrilateral have 3 obtuse angles and 1 right angle?
No a quadrilateral can't have 3 obtuse angles and 1 right angle because if a polygon did have 3 obtuse angles and 1 right angle then it would not even be a quadrilateral.
What is the area of the quadrilateral with vertices at 8 9 and 1 9 and 10 3 and 1 3?
The 4 sided quadrilateral will form a right angled trapezoid when plotted on the Cartesian plane with parallel sides of 7 units and 9 units with a height of 6 units. Area of trapezoid: 0.5*(7+9)*6 = 48 square units.
What do you call a quadrilateral that has exactly 1 pair of parallel sides?
a trapezoid is the only quadrilateral that has exactly 1 pair f parallel sides.
Facts about a trapezium?
A trapezium is a quadrilateral (has four sides). Two sides are parellel, but the other two are not. To find the area of it, the formula is: 1/2 h(a+b)
A quadrilateral with 1 right angle?
yes
