1. What should the measures of the angles be in order to ensure the accuracy of construction and therefore, stability?
The internal angles of a triangle add up to 180º
m ∠TBA = 84º
_____________
I will be drawing on the image
_______________
The sum of supplementary angles is 180º
m ∠ABL = 180º- 84º = 96º
_________________________
∠TBA and ∠LBE are vertical angles
______________________
∠ABL and ∠EBL are suplementary angles
________________________________________
∠ATL and m ∠TAE are adjacent (they have a common side)
