1 basic rules of angles There are various Rules of angles that you should know. These can be used in any geometrical diagram to work out missing angles without the diagram having to be drawn to scale. We do not need a protractor since the rule will give us the exact answer. The basic rules you should know are: Angles on a straight line add to 180 x+55 = 180 Angles on a straight line x = 125 how to see who edited a wikipedia page To work out the equation of a straight line, we need to know two things: the gradient of the line, and a point which lies on the line.

## How To Work Out Angles Of Straight Line On Cas

### Draw a triangle ABC and cut out the three angles. Step 2: Rearrange the three angles to form a straight angle on a straight line. So, the angle sum of a triangle is 180°. Task 2. To investigate if this works for all triangles, repeat the above process for four different triangles. Task 3 . Copy and complete the following statements:

- Note that, for any point in a polygon, the interior angle and exterior angle are on a straight line and therefore add up to 180°. This means that we can work out the …
