Final answer:
No single polygon is solely defined by having an angle of 180 degrees. However, option d) Straight or Linear could imply a straight angle, which is 180 degrees, though this term is not typically used to describe polygons. Option b) Regular refers to polygons where all angles and sides are equal.
Step-by-step explanation:
A polygon with an angle of 180 degrees is named based on its specific characteristics. While none of the given options directly denotes a polygon with only one angle of 180 degrees, option d) Straight or Linear could be considered somewhat relevant. No polygon can have just one internal angle of 180 degrees, as polygons are closed shapes with angles that sum up to more than 180 degrees by definition. The term linear typically refers to things arranged in a straight line, which could imply an angle of 180 degrees when two rays are collinear. When relating to option b) Regular, a polygon is regular when all angles and sides are equal, which is not necessarily related to having a single 180-degree angle.
Now, let's address the provided reference information:
- For what angle of a projectile is its range equal to zero? - The correct answer is c. 90° or 0°. At 90 degrees, the projectile is launched straight up and thus has zero horizontal range. Also, at 0 degrees, the projectile would have no vertical component, and thus no range.
- c. They point in opposite directions.
d. They are perpendicular, forming a 270° angle between each other. - These statements describe angles, but are not connected to polygons with a 180-degree angle. - a. A straight line with a negative slope. b. A straight line with a positive slope. C. It is a horizontal line at some negative value. d. A horizontal line at some positive value. - These options describe different types of lines on a graph, which are different concepts from a polygon with a 180-degree angle.
- b. They are perpendicular, forming a 90° angle between each other. - This statement talks about perpendicular lines, which form right angles, not 180-degree angles.
- b. midsagittal - A plane that divides an animal into equal right and left portions is midsagittal.
- a. rotation - Movement of a body region in a circular movement at a condyloid joint is considered rotation.
