L1: A right-angled triangle generator

A resource which can be used when teaching Pythagoras' Theorem and/or Trigonometry . Generate different right-angled triangle by dragging the corners of the triangle. The dimensions can be turned off or on by clicking on the buttons.
The trig ratios can be shown or hidden by clicking next to each trig ratio.

Click on a corner then drag left or right, up or down.

The trig ratios can be shown: click next to the one you want to see.

L3: 4 x 4 pinboards

L6: Angles generator
The labels can be dragged about

Use these buttons to select the type of angles:
Top: angles on a straight line

Middle: opposite angles

Bottom: Angles round a point

L7: Use Pythagoras' Theorem
Given the coordinates of points A and B, calculate the length of AB (Pythagoras' Theorem)

 

L8: Interactive distance- between-two-points resource: drag the two black points. The distance between the two points is worked out using Pythagoras' Theorem. Click in the big answer box to see the working out.

Use the buttons to turn the red triangle and coordinates on or off. Drag the corners of the red triangle (a large red circle will appear)
