How do you draw a triangle with the same area of a quadrilateral?
We are to construct a triangle equal in area to this quadrilateral. The areas of all triangles of same base are same if they are placed in between two parallel sraight lines. The diagonal BD is drawn. A straight line CX parallel to BD is constructed with the help of a ruler and a compass.
What is the formula of area of quadrilateral in coordinate geometry?
Area of General Quadrilateral Formula = 1/2 x diagonals length x ( sum of the height of two triangles ).
What is quadrilateral formula?
A quadrilateral is a closed figure that has four sides in it. The interior angles add up to 360 degrees. Also, for some quadrilaterals, the opposite sides are parallel and opposite angles are equal….Area Formulas of Quadrilaterals.

What is a triangle and a quadrilateral?
Introduction. A triangle is a simple closed curve or polygon which is created by three line-segments. On the other hand, in terms of Euclidean plane geometry, a polygon having four edges (or sides) together with four vertices is called a quadrilateral.
What is quadrilateral triangle?
What is a quadrilateral in math grade 6?
CBSE NCERT Notes Class 6 Maths Understanding Elementary Shapes. A quadrilateral is polygon with four sides or edges and four vertices or corners. A rectangle is a four-sided shape where every angle is a right angle i.e.90°. Also opposite sides are parallel and of equal length.
What is the area of a triangle with 4 sides?
Therefore the area of the triangle is 10. Four-sided polygons are called Quadrilaterals. They have four sides, four vertices, and four angles. The sum of the internal angles of the quadrilateral is 360 degree. Depending on the length of the sides and measure of the angle there are seven types of quadrilaterals:
How do you find the area of a quadrilateral with 3 sides?
Area of Quadrilateral Using Heron’s Formula By Heron’s formula, the area of a triangle with 3 sides a, b, and c is √s(s−a)(s −b)(s−c) s (s − a) (s − b) (s − c), where ‘s’ is the semi-perimeter of the triangle, i.e., s = (a + b + c)/2. To find the area of a quadrilateral using Heron’s formula,
How to find the area of a quadrilateral using Heron’s formula?
To find the area of a quadrilateral using Heron’s formula, Divide it into two triangles using a diagonal (Use the diagonal whose length is known). Apply Heron’s formula for each of the triangles to find its area. Add the areas of two triangles which gives the area of the quadrilateral.
How do you find the common base of a quadrilateral?
We can view the quadrilateral as a combination of 2 triangles, with the diagonal PR being the common base. h 1 and h 2 are the heights of triangles PSR and PQR, respectively. Area of quadrilateral PQRS is equal to the sum of the area of triangle PSR and the area of triangle PQR.
