Triangles and quadrilaterals
on pinboards

Q27: Pinboards
Make triangles and quadrilaterals on pinboards. Loads of uses: properties of triangles and quadrilaterals, symmetry, angles, area....
Choose the size of the pinboardChoose the size of the pinboard with these buttons: 3x3, 4x4 or 5x5. One set of buttons for triangles, the other for quadrilaterals. Drag the corners of the shape.

Brightness buttons
Use these buttons to change the brightness of the nails (dots) on the pinboard,
the rings on the corners of the shapes and the grid.

Estimate, draw and measure angles

Q5: Place in order of size a set of angles each less than 180 degrees.

Q6: Say whether an angle is acute or obtuse and estimate the size to the nearest 5 degrees.

 

Measuring an angle

Q7: Measure an angle. An angle is randomly generated; keep clicking until you are happy with the angle. The angle can be estimated or measured. Move the angle by dragging its 'corner'. Reveal the protractor and move it into position then rotate it to fit over the angle. The angle can also be rotated.

Q7 version 2: Measure an angle version 2.
The rotate buttons only appear when the protractor is placed in the correct position on the angle. The protractor rotate buttons only need to be pressed once. The protractor will keep rotating until it is in the correct position.

 

 

Measuring length with a ruler

Q8: Measure the length of each of three lines. Drag the ruler into position.

Q9: Measure the length of each side of a quadrilateral. A quadrilateral is randomly generated; keep clicking until you are happy with the quadrilateral. Drag the ruler to measure one side of the quadrilateral. Use the rotate buttons to line up the ruler and the side. Use the zoom button to zoom in or out. The quadrilateral can be moved by dragging the top left corner.

 

Angles on a straight line

Q10: Calculate angles on a straight line.

Shapes made from squares

Coordinates

Drag the polygons/points about.
Hide or show the coordinates by clicking in the panel to the right of the polygons/ABC labels.
Hide or show the polygons/points by click on the polygon/ABC labels.
Hide or show all the coordinates and/or points by clicking on the hide/show buttons.

Q29: Describe and find the position of polygons using, for example, (B, 5)
Q30: Describe and find the position of polygons using coordinates in the first quadrant


Q31:
Read and plot points using coordinates in the first quadrant
Q32: Read and plot points using coordinates in all four quadrants


The coordinates of three of the vertices of a square or rectangle are given:

. . what are the coordinates of the fourth vertex? . . what is the area of the rectangle? ..what is the perimeter of the rectangle?
Q11:
Positive coordinates

Identify the coordinates

The coordinates of some of the vertices of a shape are given, the numbers on the axes and the grid are hidden. What are the coordinates?
Drag the shapes or click on the 'change' button.

Q12: Positive coordinates

Q13: All four quadrants

Q14: Shapes made from squares in all four quadrants

Q15: Interactive coordinates and reflections resource: drag the shape with the black outline. The coordinates can be worked out without showing the numbers on the axes or the grid. Click next to the letters to reveal the coordinates.
Use these buttons to change the options

Show or hide the grid, the numbers on the axes, the mirror line or the reflections of the shapes.

The mirror line can be dragged to the left and right.

Rotate a triangle about a point

Q19: Interactive rotation resource: drag the yellow triangle and watch the transformations. Move the centre of rotation (the red point). Use the buttons to show or hide the rotations. Turn the labels and coordinates on or off.

Transparent trianglesThe transparent triangles can be used as 'answers'. Select the triangle and drag it to where you think the rotation is going to be.

 

 

Reflect, rotate and translate a triangle

Q20: Interactive transformations resource: drag the yellow triangle and watch the transformations. Use the buttons to show or hide the translation, reflections or rotations. Turn the labels and coordinates on or off.

Transparent trianglesThe transparent triangles can be used as 'answers'. Select the triangle and drag it to where you think the reflection or rotation is going to be.

 

Rotational symmetry and rotations about a point

Q24: Rotational symmetry and rotating shapes
Rotate through 90 degrees.

Use the slider to determine the angle and select the shape using the shape buttons.
The shape's outline can be shown so that rotational symmetry can be investigated. Click on a shape button to reset the shape.
The shapes can be dragged about so that they can be rotated about a different corner, for example.

Hide or show the outline of the shape, its shadow, its eyes and the grid. Showing the eyes is useful to see which way up the shape is. The shadow shows from where the shape has been moved.

Q26: Rotation problem-solving activity
A square made up of nine smaller squares (on the left) contains four shapes. The square on the right shows the same four shapes in the same squares, only one of the shapes is visible. This square can be rotated. The task is to draw the three missing shapes.
Click on the squares in this button
Click on the squares on this button to hide or show what is in each square.

Link to the activity
Click in the top right quadrant. The tiles will be reflected in the other three quadrants.

Keep clicking on a tile to rotate it.

Q21: Make reflection patterns with Truchet tiles
In 1704, Sebastien Truchet created all the possible patterns formed by tiles like this: Truchet tile

Use these buttons to change the tile usedFirst select select the tile.

Use the white tile to delete a tile.

Christmas maths
Have a look at Angles in Christmas Trees
A Christmas tree drawn using Logo.

HollyQ23: Angles in Christmas trees
Two Christmas maths activities:
Use the computer programming language Logo to draw a Christmas tree.
First decide on the internal angle of the pointy bits on the tree and an angle in the tub. Then work out all the other angles. Write Logo procedures to draw the tree. It will soon show whether you've worked out all the angles.

Instead of using Logo, draw the Christmas tree accurately using a ruler and protractor. If you don't get back to the start it's not accurate!
