A guide point is a finite dashed line, whereas a guide line is infinite. Tip: When you measure from an end point inference and create a guide, SketchUp creates a guide point, as shown in the figure.

(Optional) To move your guide line a precise distance from the starting point, type a number and unit and then press Enter.

(See Adding Text to a Model for information about labeling distances in your model.) In the following figure, the guidelines mark the distance 3 feet from the interior walls.

If you pressed Ctrl in the preceding step, a guide line appears as a dashed line that reaches into infinite 3D space (at least within your model). The distance from the start point appears in the Measurements box.

Click at the ending point of your measurement.

A plus sign appears next to your Tape Measure cursor ( ).

(Optional) To create a guide line, press Ctrl (Microsoft Windows) or Option (macOS).

The Measurements box dynamically displays the length of your measuring tape.

You'll see a notification at the cursor that the inference is locked. The up arrow locks the blue axis, the left arrow locks the green axis, and the right arrow locks the red axis.

Tap a directional button while measuring to lock an axis.

In the figure, you see measuring tape aligned to the red axis.

The measuring tape line changes color to match an axis colors when it is parallel to any axis.

Tip: Here are a few tips to help you move the Tape Measure cursor through 3D space: Measuring Angles and Distances to Model Precisely

I have tended to go anticlockwise in the diagrams. Angles can be measured clockwise or anticlockwise on the empty protractor and there are no extra rules about this to be remembered. (1988) Preparing to teach angle, Open University See: DfE (2020) Guidance for teaching mathematics in primary schools available at: In fact, if the radius is 1 this gives the radian measure of an angle but is hard to do ‘in the field’. Additionally, Jo Morgan collected some other useful resources in a Maths gems post on her excellent Resourceaholic website.

You can find more tasks for developing thinking about angle in the teacher resources here. What is the minimum number you would need to measure to know all of the rest? Work out the angles in the diagram – predict them first. The purple line segments in this image are parallel. If you mark a point a point every 40° you create a 9-dot geoboard. As the empty protractor is circular, you can use it to create a circular geoboard and then all the angles will be nice numbers so pupils can measure with confidence. Here’s a parallel lines task to get you started.

The empty protractor is a simple tool that can help learners develop their conceptual understanding of angles and procedural fluency with measuring and drawing of angles that are crucial for reasoning and problem solving.Įxcitingly, if you’d like to try out an empty protractor with your pupils, they are now available to buy alongside some guidance for how to use them and guidance for tasks your pupils can explore whilst developing their expertise with angles. Pupils can draw the turn of the arc, which may be helpful with measuring and understanding angles. Pupils then count around to the required line. However, learners quickly conjecture that measuring from one of the angle’s longer lines is easier (although using a pencil to extend the lines (arms) of the angle negates this need). Learners count the degrees so there is no need to place any particular protractor line on top of the angle line. Rather than a long list of steps to remember, learners only need one to place the centre at the point of the angle they wish to measure.

Draw a line through the marked point to the vertex.

Place the centre of the protractor on the vertex of the angle.
