In Year 4, children are taught the term quadrilateral and will be asked to determine whether a certain shape is a quadrilateral or not. In Year 5 , children will be asked to draw shapes to a given criteria for example: draw a quadrilateral with an obtuse angle and a right angle. They will also need to use their knowledge of quadrilaterals to find missing lengths and angles. They will use this information to find missing angles in quadrilaterals.

Children might be asked show they understand what a quadrilateral and what quadrilaterals' properties are is by answering a Carroll diagram question like this one: Answer: The first and second shapes cone and cylinder need to go in the right-hand column.
The third shape the cuboid needs to go in the left-hand column. Answer: Child would need to draw a line directly through the centre of the shape as accurately as they could manage , either vertically or horizontally. What questions on quadrilaterals might be in Y6 maths SATs? Another question type might require your child to draw a quadrilateral following specific instructions, for example: Answer: Parallel sides are sides that are always the same distance apart and can never meet.
The answer to this question could be completing the diagram to make a rectangle, or drawing a shape with two right angles and one acute angle, similar to the shape shown in the previous question. Help your child to learn about quadrilaterals at home Challenge them to go around the house looking for different quadrilaterals.
Can they name each one? Could they also find some 3D shapes, such as a cereal box, a cone or a sphere? Which ones have square or rectangular faces? How many of these faces do they have? Notice that each figure has four straight sides and four angles. Interior Angles of a Quadrilateral. Consider the two examples below. You could draw many quadrilaterals such as these and carefully measure the four angles. Any quadrilateral can be divided into two triangles as shown in the images below.
In the first image, the quadrilaterals have each been divided into two triangles. The angle measurements of one triangle are shown for each. Specific Types of Quadrilaterals. These quadrilaterals are called parallelograms They take a variety of shapes, but one classic example is shown below.
Imagine extending the pairs of opposite sides. They would never intersect because they are parallel. Notice, also, that the opposite angles of a parallelogram are congruent, as are the opposite sides.
The parallel sides are also the same length: and. These relationships are true for all parallelograms. There are two special cases of parallelograms that will be familiar to you from your earliest experiences with geometric shapes. The first special case is called a rectangle. By definition, a rectangle is a parallelogram because its pairs of opposite sides are parallel. A rectangle also has the special characteristic that all of its angles are right angles; all four of its angles are congruent.
The other special case of a parallelogram is a special type of rectangle, a square. A square is one of the most basic geometric shapes. It is a special case of a parallelogram that has four congruent sides and four right angles.
A square is also a rectangle because it has two sets of parallel sides and four right angles. A square is also a parallelogram because its opposite sides are parallel. Another quadrilateral that you might see is called a rhombus. All four sides of a rhombus are congruent. Its properties include that each pair of opposite sides is parallel, also making it a parallelogram.
In summary, all squares are rectangles, but not all rectangles are squares. All rectangles are parallelograms, but not all parallelograms are rectangles.
And all of these shapes are quadrilaterals. A circle that passes through three of the vertices is either too large to pass through the fourth blue circle at the left or too small to pass through the fourth red circle at the right. In addition to circumscribing circles around a quadrilateral drawing circles around a quadrilateral, touching each vertex , it is sometimes possible to inscribe a circle draw a circle within a quadrilateral so that each side of the quadrilateral is tangent to the circle.
This group of quadrilaterals has no special name of its own, but includes kites, rhombuses, and squares along with other quadrilaterals that have no particular name. Investigations: When investigating special quadrilaterals and their properties, students find many ways to distinguish quadrilaterals. Some productive explorations ask students to look for special properties of angles congruent or supplementary , sides parallel, perpendicular, or congruent , and diagonals perpendicular, bisecting, or congruent.
Shape: Quadrilateral. Shape: Quadrilateral Topics: Mathematical Language. Quadrilateral A quadrilateral is a polygon that has exactly four sides. Meaning A quadrilateral is a polygon that has exactly four sides. Some examples of quadrilaterals: 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.
Some K-8 curricula also include kites G and, in some definitions H. Classification Just as triangles and quadrilaterals are special types of polygons, there are many subclasses of quadrilaterals. Children can also experiment with this idea by coloring or labeling the corners of a quadrilateral , cutting the corners off … , and fitting the colored vertices together to show that they all fit snugly around a point.
Special topics rarely in elementary or middle school Cyclic quadrilaterals: For some quadrilaterals, it is possible to pass a single circle through all four of its vertices. Related posts. Shape: Equiangular Read more.
