Which statements are true for all rectangles a. all sides are equal in length b. all angles are right angles c. all angles are acute d. two angles are obtuse and two angles are acute

I believe the correct answer is B.  

Step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
