|Sum angles in triangle||Maths||Geometry|
The sum of the angles in a triangle is always 180°.
- Move the vertices of the triangle with the mouse
- See the values of the angles with up to 5 decimal places
Explain the figure.
Check that the sum is always 180º no matter the precision of the measurement.
Try to design these triangles as well: rectangular, equilateral, etc.
Is it harder to do when you increase the number of decimal places? Why?
