  • 1 How many degrees is this angle? How do you know?

    A triangle with one 90-degree angle, one 60-degree angle, and one 30-degree angle. An arrow points to the 30-degree angle.

  • 2 How many degrees is this angle? How do you know?

    A triangle with three 60-degree angles. An arrow points to one of the angles.
