Final answer:

The sum of the angles in a triangle is always 180 degrees. Find the missing angle by subtracting the sum of the known angles from 180. Follow these steps while working on your worksheet Section A.

Step-by-step explanation:

From a mathematical point of view, the sum of the angles in a triangle always equates to 180 degrees. You can find the missing angles by subtracting the available angle measurements from 180.

For example, in a triangle with one known angle of 50 degrees, and another of 80 degrees, the missing angle could be found by the following steps:

  1. Add the two known angles together (50 + 80 = 130).
  2. Subtract the result from 180 (180 - 130 = 50).
  3. The result is the missing angle, 50 degrees.

You can follow these steps while working on your worksheet Section A to find the missing angles in the triangles.
