Caroline drew two triangles and used them to construct a rhombus with two acute angles and two obtuse angles. Which could be
one of the triangles she used?

And there’s one triangle that not in the photo but the degrees are 30 and 60

What is the difference between regular convex and concave polygons

Can some one me with these questions

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
