We can draw exactly one triangle whose angles are 70°, 30° and 80°. Is the given statement true or false?

Solution:

We know that

Infinite triangles can be drawn whose angles are 70°, 30° and 80° having different sides.

Therefore, the statement is false.

✦ Try This: A cone has __________vertex, __________edge and __________faces.

We know that

A cone is a three-dimensional shape that has a circular base and it narrows down to a sharp point called a vertex.

A cone has one face and a vertex.

There are no edges for a cone.

Therefore, a cone has 1 vertex, no edge and 1 face.
