Practice set 1 Problem 1A Is the following figure a polygon Choose 1 answer: Yes A Yes No B No Want to learn more about recognizing shapes Check out this video. These can be cut-outs or graphics on the page, depending on the needs of the students. What is a polygon A polygon is a closed figure with at least 3 3 straight sides. It is a good idea to have a whole-group discussion about this task to be sure that students understand the relationship between these different quadrilaterals.įor students who need more scaffolding, the teacher can provide a bank of shapes for them to sort as âexamplesâ and ânon-examplesâ in part (a). 14 The midpoints of the sides of any quadrilateral (convex, concave or crossed) are the vertices of a parallelogram called the Varignon parallelogram. Students should take care to draw their figures with a straight-edge so that they can draw precise shapes. There are six special quadrilaterals with different properties. Students should be encouraged to work in small groups and use the correct vocabulary as they talk together about classifying shapes. By drawing examples and non-examples for each kind of shape, students get an opportunity to explore their individual properties before relating their knowledge of all three to the defining attributes of a square. The most common include squares and rectangles, but there are loads of others as well. A concave quadrilateral has one reflex angle, or an angle greater than 180 degrees. The most symmetric shapes, as their name implies, formally date back to the Greek philosopher Plato (428-348 BCE), though most of them were recognized, or at least crafted, even earlier. The figure below is an example of a quadrilateral. An equivalent condition is that opposite. Question What is a polygon with 4 sides called A a circle B a triangle C a quadrilateral D a pentagon Solution The correct option is B a quadrilateral A four sided polygon is called a quadrilateral. In this task, students ultimately use the definitions they are given for three types of quadrilaterals and what they know about parallel sides to identify that a square fits all the definitions and explain why. In addition a quadrilateral can be convex or concave. Square (regular quadrilateral): all four sides are of equal length (equilateral), and all four angles are right angles. This task builds on the geometric knowledge that students developed in 2nd grade (2.G.1).
