Students are tasked with labeling a variety of angles. They need to identify each of the seven angles as acute, right, obtuse, or straight.
Angles measure the space between two lines or rays that meet at a corner or vertex. They're named after the number of degrees or parts of a circle they cover. For example, a right angle is 90 degrees and looks like the corner of a square. A straight angle is 180 degrees and looks like a straight line. An acute angle measures less than 90 degrees. In contrast, an obtuse angle measures more than 90 degrees but less than 180 degrees, making it appear wider or more spread out than an acute angle.
