Question

How many triangles can be constructed with angles measuring 80 degrees 80 degrees and 40 degrees

Answer 1

None

Explanation:

The angles inside a triangle add to 180. If the angles are 80, 80 and 40, then they must add to 180 to form a triangle.

80+80+40 = 200

This can't be a triangle.

Answer 2

Zero.

The sum of these angles is 200°. The sum of angles in a triangle must be 180°. These angles cannot be used to form a triangle.
