 \u003Cbr>Step 1:A shape with rotational symmetry will sill look the same after it has been rotated(turned  \u003Cbr>around a point)by less than one fullturn.The number of times it matches up with the  \u003Cbr>original shape during the rotation is called the order of symmetry.  \u003Cbr>To work out the rotational symmetry,imagine tuming the shape around the centre point.  \u003Cbr>Keep track of one of the points so you can see when a full turn is complete.  \u003Cbr>Step 2:Count the number of times the shape matches up with the original.  \u003Cbr>The shape will match up 4 times.This means it has rotational symmetry order 4.  \u003Cbr>Answer=4   |\n| --- |\n\n\n|  |  |  |  |  |  |  |\n| --- | --- | --- | --- | --- | --- | --- |\n|  |  |  |  |  |  |  |\n\n\n|  |  |  |  |  |  |  |  |\n| --- | --- | --- | --- | --- | --- | --- | --- |\n|  |  |  |  |  |  |  |  |\n|  |  |  |  |  |  |  |  |\n|  |  |  |  |  |  |  |  |\n|  |  |  |  |  |  |  |  |\n\nGuided Example  \nDraw three lines of symmetry on the shape below.  \nStep 1:Draw one line of symmetry that cuts the shape in half.  \nStep 2:Draw another line of symmetry that cuts two sections in half.  \nStep 3:Draw the third line of symmetry to cut the remaining two sections in half.All the sectionsshould be the same.  \nNow it's your turn!If you get stuck,look back at the worked and guided examples.  \n1.Draw the stated number of lines of symmetry on the shapes below:  \na)One line.  \ne)Four lines.  \nf)Four lines.  \nb)One line.  \nc)Two lines.  \n9)Five lines.  \n5  \nd)Two lines.  \nh)Six lines.  \n3  \n4  \n6  \n6  \n## Section B\n\n\n| Worked Example  \u003Cbr>Define the angles below as acute,obtuse,right-angled or reflex.  \u003Cbr>Step 1:The first angle is acute.  \u003Cbr>It is acute because the angle is less than a right-angle.  \u003Cbr>Step 2:The second angle is reflex.  \u003Cbr>It is reflex because it is more than a straight line,but less than a full turn.  \u003Cbr>Step 3:The third angle is a right-angle.  \u003Cbr>We can tell that it is a right-angle because the angle is marked with a square symbol  \u003Cbr>Step 4:The fourth angle is an obtuse angle.  \u003Cbr>It is obtuse because it is more than a right-angle but less than a straight line.   |\n| --- |\n\n\n| Guided Example  \u003Cbr>Draw an acute angle and an obtuse angle.  \u003Cbr>Step 1:An acute angle is less than a right-angle.Draw two lines connected at a point and mark the  \u003Cbr>angle.  \u003Cbr>:90°  \u003Cbr>Step 2:An obtuse angle is less than a half-tum but more than a right angle.Draw two lines  \u003Cbr>connected at a point and mark the angle.  \u003Cbr>180°  \u003Cbr>90°   |\n| --- |\n\nNow it's your turn!If you get stuck,look back at the worked and guided examples.  \n2.Draw the angles below:  \na)An acute angle.  \nLess than 90°  \n上  \nb)A reflex angle. 6。。te  6°  \nc)A half-turn.180°-straignt Une180  \nd)A full turn.360°360  \n3.The diagram below shows a triangle with three angles marked.Daniel says  \n“The size of angle x is 76°.”  \nIs Daniel correct?Give a reason for your answer.  \nx=123°-57 十5班19+38十x=180Anges in  triangle acd upo8  \nDaniel is  wrong,  \nX=123°.  \n## Section C\n\n\n| Worked Example  \u003Cbr>Describe the following lines using the words pa","cbCaibjilvdiM7qW","https://ap.wps.com/l/cbCaibjilvdiM7qW","pdf",1047660,11,"English","# Section A\n## Worked Example\n## Guided Example\n# Section B\n## Worked Example\n## Guided Example\n# Section C\n## Worked Example\n## Guided Example","[{\"question\":\"How do you find the order of rotational symmetry of a shape?\",\"answer\":\"Imagine rotating the shape about its centre point and count how many times it matches the original.
