Question

How many triangles can be constructed with angles measuring 60º, 60º, and 40º? a more than one b none c one

Answer 1

None

Explanation:

All angles must add up to 180 in a triangle. 60+60+40=160. therefore, no triangles can be made with these angles.

Answer 2

Okay so we know that all three angles of a triangle should add up to 180 degrees.
60 + 60 + 40 = 160
This only adds up to 160 degrees so the answer is none. This kind of triangle does not exist.
