43Activity 3QuadrilateralsRemember, a quadrilateral is a closed shape with 4 straightsides.1. Draw as many different quadrilaterals as you can think of in your book.2. Copy and complete the sentences.a. A -------- has 5 straight sides.Draw 3 of these shapes in your book.b. A -------- has 6 straight sides.Draw 3 of these shapes in your book.c. A -------- has 7 straight sides.Draw 3 of these shapes in your book.A new 2D shape:the octagonTom Newby School. Grade 6 Mathematics 2016 – Term 2 Properties of 3D Shapes

451. Draw each shape and match it to the correct description.It has 5 straight sides.It has 5 angles.It has 6 straight sides.It has 2 long sides and 2 short sides.It has 6 angles.It has 4 right angles.It has 7 straight sides.It has 7 angles.It has 8 straight sides.It has 8 angles.It has 3 straight ( ) sides.It may have 1 right angle.It has 2 long sides and 2 short sides.It has no right angles.It has 4 straight angles.It has 4 angles.Activity 5AnglesRemember: An angle is formed when 2 straight lines meet each other.The lines are called the arms of the angle.An angle is the amount of turning that the arms do.The symbol for angle is ے .You can make your own right angle measure.Types of angles:Acute angle:Acute angles are smaller than right angles.Right angle:Right angles are 90 .Tom Newby School. Grade 6 Mathematics 2016 – Term 2 Properties of 3D Shapes
46Obtuse angles:Obtuse angles are bigger than a right angle.Straight angles:Straight angles are 2 right angles.Reflex angles:Reflex angles are bigger than a straight angle.Revolution:A revolution is a complete circle.1. Write the letter and the name of each angle.a.b.c.d.Tom Newby School. Grade 6 Mathematics 2016 – Term 2 Properties of 3D Shapese.
47Activity 6Remember us?I have 4 sides of length. I have4 right angles.I have 2 long sides of length and 2 shortsides of length.I have 4 right angles.1. Draw the above two shapes in your book using the correct Mathematical symbols toshow the above information.2. What does parallel mean?Parallel lines are an equal distant apart and will NEVER touch.3. Can you think of examples of parallel lines in real life, like the sides of a ladder?Write your objects in your work book.Another new 2D shape:the parallelogram .Parallelograms have: opposite sides that are equal in length.opposite sides that are parallel.no right angles.Tom Newby School.
