Yes
An acute triangle.
You cannot.

Acute or obtuse: Yes. Straight: No.
It's entirely possible to draw a quadrilateral with 3 acute angles.The fourth angle must be obtuse or reflex, but so what ? !
Oh, what a lovely question! You see, when you draw a reflex angle, it always opens up more than 180 degrees. So, the other angle formed by the arm will always be acute, which means it will be less than 90 degrees. Just remember, every angle has a story to tell on your canvas of mathematics.

Yes. Every triangle with an obtuse angle must have two acute angles.
yes. if the reflex angle is 260 degrees, the other is 100 which is obtuse
A bit like a chevron or an arrowhead.
Yes, it is possible to draw a quadrilateral with a reflex angle and an obtuse angle. A reflex angle measures more than 180 degrees, while an obtuse angle measures between 90 and 180 degrees. To create a quadrilateral with these angles, you can draw a shape with one reflex angle (greater than 180 degrees) and one obtuse angle (between 90 and 180 degrees), along with two acute angles (less than 90 degrees).
An acute angle has less than 90 degrees, an obtuse angle has greater than 90 degree but less than 180 degrees. A reflex angle has greater than 180 degrees.When in doubt, google image search.
