Using the given information, in this case ∠CAD = 30° and ∠GAB = 80°, can you find the remaining unknown angles formed around point A without using a protractor? 1. Tap and write the unknown angles without using a protractor. (These angles are not to scale so you won’t be able to measure them!) 2. Explain how you could determine the unknown angles, using mathematical reasoning to justify your explanation. It is important to use mathematical language and mention all three angle relationship generalisations. 3. Tap to upload your work.
