Question
We can draw exactly one triangle whose angles are 70°, 30° and 80°

Answer

False.

Solution:

Though the angles are unique for the triangle, but the length of the sides can differ and hence the number of triangles that can be drawn with this angles will also be more.

So the given statement is false.

We can draw more than one triangle whose angles are 70°, 30° and 80°.
