ASA and AAS are two postulates that help us determine if two triangles are congruent. ASA stands for “Angle, Side, Angle”, while AAS means “Angle, Angle, Side”. ... ASA refers to any two angles and the included side, whereas AAS refers to the two corresponding angles and the non-included side
Step-by-step explanation:
Angles 1 and 2 are linear, meaning that they are supplementary, or add up to 180 degrees. We already know that angle 1 = 72 degrees. So, to find angle 2, take 180 and subtract 72 from it to get: 180 - 172 = 108 degrees. The answer is B.
