What are the coordinates of quadrilateral ABCD?

8 The coordinates of quadrilateral ABCD are A(-1,-5), B(8,2), C(11,13), and D(2,6). Using coordinate geometry, prove that quadrilateral ABCD is a rhombus. [The use of the grid is optional.]

What are the coordinates of the vertices of quadrilateral?

Coordinates of the vertices of a quadrilateral are (2, -1), (0, 2), (2, 3) and (4, 0). The angle between its diagonals will be. Solution: Let A(2, -1), B(0, 2), C(2, 3) and D(4, 0) be the vertices of a quadrilateral.

How do you classify a quadrilateral with coordinates?

A parallelogram is a quadrilateral with two pairs of parallel sides. A quadrilateral is a closed figure with four sides and four vertices. A rectangle is a quadrilateral with four right angles. A rhombus is a quadrilateral with four congruent sides.

What are the 4 vertices of a quadrilateral?

A quadrilateral is a polygon that has exactly four sides. (This also means that a quadrilateral has exactly four vertices, and exactly four angles.) Discussions of 2-D shapes sometimes refer only to the boundary (the line segments that form the edges of the figure) or to the interior as well.

Which statement explains why △ ABC is congruent to △ A B C △ A B C?

Which statement explains why △ABC is congruent to △A′B′C′? You can map △ABC onto △A′B′C′ by reflecting it over line y = x and translating it 5 units right, which is a sequence of rigid motions.

Which of the following ways can prove that quadrilateral ABCD is a parallelogram?

If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram. If — AB ≅ — CD and — BC ≅ — DA , then ABCD is a parallelogram. If both pairs of opposite angles of a quadrilateral are congruent, then the quadrilateral is a parallelogram.

What kind of quadrilateral is ABCD?

A quadrilateral is called a parallelogram, if both pairs of its opposite sides are parallel. AB ∥ DC and AD ∥ BC. So, ABCD is a parallelogram. A parallelogram having all sides equal, is called a rhombus.

How do you name vertices of a quadrilateral?

The endpoints of the sides of polygons are called vertices. When naming a polygon, its vertices are named in consecutive order either clockwise or counterclockwise. Consecutive sides are two sides that have an endpoint in common. The four‐sided polygon in Figure could have been named ABCD, BCDA, or ADCB, for example.

How do you find the area of a quadrilateral with 4 vertices?

If the diagonal and the length of the perpendiculars from the vertices are given, then the area of the quadrilateral is calculated as: Area of quadrilateral = (½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices.

How many vertices does a quadrilateral ABCD have?
