A teacher asks three different students to draw a triangle with the angles 30o, 70o, and 80o. If they draw the angles correctly,
which statement is true about the three angles drawn? a The triangles do not have to be congruent because the side lengths are not given, so the angle measurements can form many different angles.
b The triangles must be the same size and shape because 30o+ 70o > 80o, which makes a unique triangle.
c There is not enough information to draw any conclusions about the relationship between the triangles the students draw because the drawings are not given.
d The triangles must be congruent because the three angle measurements add up to 180o, which makes a unique triangle.
