Question

1. Solomon says, "I have drawn a triangle. It has one angle of 30° and another

Answer 1

Triangles = 180 degrees
Angle 1 = 30 degrees
Angle 2 = 40 degrees
Therefore 180 - 30 - 40 = 110 degrees = Angle 3

It is correct that given two angles of a triangle, the third angle must be 180 degrees - the other two angles. So Adeline’s triangle will have the same angles.

However, Solomon’s triangle & Adeline’s triangle could be vastly different sizes. And since that’s possible, the two triangles cannot be guaranteed to be congruent.
