To find the measure of the third interior angle of a triangle when two angles are known, you can use the property that the sum of all interior angles in a triangle is always 180°.
Here is how to calculate it step-by-step:
- First, add the measures of the two given angles:
- 34° + 34° = 68°
- Next, subtract the sum from the total sum of the angles in the triangle:
- 180° - 68° = 112°
- Thus, the measure of the third interior angle is 112°.
