c. right
d. straight

1. which best describes the angle shown?

image of angle at e with rays ed, ef
a. acute
b. obtuse
c. right
d. straight

Explanation:

Question 2

An acute angle is less than \(90^\circ\), an obtuse angle is greater than \(90^\circ\) but less than \(180^\circ\), a right angle is exactly \(90^\circ\), and a straight angle is \(180^\circ\). The angle at \(B\) (between \(BA\) and \(BC\)) appears to be less than \(90^\circ\), so it is acute.

The angle at \(E\) (between \(ED\) and \(EF\)) appears to be greater than \(90^\circ\) but less than \(180^\circ\). An obtuse angle fits this description (acute is \(<90^\circ\), right is \(=90^\circ\), straight is \(=180^\circ\)).

Answer:

A. acute
