Convex, Concave and Intersecting Quadrilaterals Another way to classify the types of quadrilaterals are: Convex Quadrilaterals: Both the diagonals of a quadrilateral are completely contained within a figure. Concave Quadrilaterals: At least one of the diagonals lies partly or entirely outside of the...
As shown in the diagram below, △BEF and △DEF are two identical triangles. The total are a of△AEH, △DHG and △GF C is 6cm2. If we add this (6cm2) to the are a of the quadrilateral EFHG, we obtain of the are a of △ A B C. What is the are a of △ABC, in cm2?
Now we are asked to find its area. Unfortunately, we are not given any formula for calculating the area of this kind of quadrilateral. (You might remember that its technical name is a trapezoid, but in fact we don't need to know anythingspecial about trapezoids to solve this problem.)...
If we convert all the four angles of a parallelogram into right angles, which quadrilateral will be obtained? What is the name of the quadrilateral whose four sides are equal? How many sides are there in any quadrilaterals? How many angles are there in any quadrilaterals?
There are two main parts related to an angle - the arms and thevertex. Arms of the Angle The two rays which join at a common point to form the angle are called thearms of the angle. Observe the figure given below which shows that OA and OB are the arms of the angle AOB. ...
Are all polygons quadrilaterals? What do you notice about lines of symmetry in regular polygons? Identify the Geometry term described. A six-sided polygon. If the pattern of polygons continues, which polygon will have 12 sides? polygon 1 = A 3-sided triangle, polygon 2 = A square, polyg...

A parallelogram is a specific type of quadrilateral with opposite sides parallel and equal in length, while a quadrilateral is any four-sided polygon, including rectangles, squares, and trapezoids.
The rectangles are the quadrilaterals in which the four inner angles are of the same measure and, the facing sides are parallel and identical. The vertices of a rectangle are the intersections of the two sides of the rectangle and, they...
