Question

1. select all that apply: in sas, the a stands for included angle. the included angle is where the two sides meet the angle formed by the two sides the angle at the end of one of the sides but not touching the other side the angle between the two sides

Explanation:

To determine the correct options for the included angle in SAS (Side - Angle - Side) congruence criterion:

• The included angle is the angle that is formed where the two sides meet. This is because when two sides of a triangle meet at a vertex, the angle at that vertex is between those two sides.
• "The angle formed by the two sides" is also correct as the two sides coming together form the angle.
• "The angle between the two sides" is a direct description of the included angle as it lies in the space between the two sides.
• The option "the angle at the end of one of the sides but not touching the other side" is incorrect because the included angle must be related to both sides, not just one.

Answer:

• where the two sides meet (checked)
• the angle formed by the two sides (checked)
• The angle between the two sides (checked)
