What are the diagonals in a quadrilateral?
The diagonals in a quadrilateral are the (usually imaginary) straight lines that go through the inside of the shape from one vertex to another. For example, say you have a square (a quadrilateral) consisting of points A, B, C, and D. They are all connected on edges going A to B, B to C, C to D, and D to A. Envisioning this shape in your mind, you would likely imagine the inside of the square being blank. There would be two diagonals in a shape like this (as well as in every quadrilateral) being the lines going from A, through the center of the square, to C, and the other being the line going from B, through the center, to D.
How can you tell the difference between rhombus and rectangle?
A rectangle has 4 corners that are each 90°.A rhombus has 2 acute angles x < 90°, & 2 obtuse angles, x > 90° .Rectangle a----b rhombus a--b| | / \c----d c------drectangle (a+b) (a+c) (a+d) (b+a) (b+c) (b+d) (c+a) (c+b) (c+d) (d+a) (d+b) (d+c) = 180°rhombus (a+c) (a+d) (b+c) (b+d) = 180°Answer:The definition of rhombus is a quadrilateral whose four sides all have the same length without a requirement of the relation of the adjacent angles . A rectangle is any quadrilateral with four right angles without a requirement on the relationship of adjacent sides.This definition allows one quadrilateral (the square) to be both a rectangle and a a rhombus. The square is a rectangle with all sides being equal and a rhombus with all angles being equal (90o)
When can this be true abcd is a quadrilateral does a plus b plus c plus d equals 180?
No; it is false. The sum of all the angles of a quadrilateral always equals 360o.
How many ways can you pair three animals?
Three possible ways. Let's name our animals A, B, and C: A-B A-C B-C
How do you find the area of a four sided polygon?
There is no simple way to find the area of a general quadrilateral. It will require information about the lengths of the sides and a pair of opposite angles. The quadrilateral is divided into two triangles by joining the other pair of angles and using the trigonometric formula for the area of each triangle.So, suppose the sides of the quadrilateral are of lengths a, b, c and d unitsthe angle between a and d is A; andthe angle between b and c is CthenArea = 1/2[a*d*sin(A) + b*c*sin(C)] square units.
What is the proper name of the quadrilateral below a parallelogram b triangle c square d rectangle?
parallelogram
Quadrilateral ABCD has vertices A(6, -3), B(8, -2), C(10, -6), and D(8, -7). What is the most inclusive name for this quadrilateral?
rectangle
What is diagonal of quadrilateral?
A quadrilateral is an object formed by four straight lines - two of which meet at an angle. A diagonal is one of the lines which go from one angle to the one other angle in the quadrilateral which it is not already connected to. If the angles of the quadrilateral are A, B, C and D, and A is connected by a straight line to B and D then the diagonal is a line between A and C. A--B | \ | D--C
Which word does not apply to every rectangle A. Quadrilateral B. Polygon C. Rhombus D. Parallelogram?
It is C. Rhombus
What is the most precise name for a quadrilateral ABCD with vertices A 5 2 B 5 2 C 0 2 D 0 2?
If A is at (5, 2) and B is at (5, 2) then they are both the same point; and if C is at (0, 2) and D is at (0, 2) then they are both the same point; and the quadrilateral is a [straight] line.
If quadrilateral ABCD is a parallelogram in which angle B equals 100 degrees how many degrees would be a plus c?
A = C = 180 - B = 80 So A + C = 160
What is the most precise name for a quadrilateral ABCD with vertices A-5 -2 B-5 2 C 0 2 D 0 -2?
Rectangle

Quadrilateral abcd is a parallelogram in which b equals 100 degrees.a plus c equals?
160 degrees.
ABCD is a quadrilateral does A plus B plus C plus D always is 360 degrees?
Yes.
When can this be true abcd is a quadrilateral does a plus b plus c plus d equals 180?
No; it is false. The sum of all the angles of a quadrilateral always equals 360o.
