Right Angles
In this right angles worksheet, students review various images of right angles. Students then find the angles and right angles for the given shapes and write them on the lines.
Curated OER
Acute, Right or Obtuse
In this angles learning exercise, students solve 4 problems in which angles are analyzed and classified as acute, obtuse, or right. No examples are provided.
Curated OER
Inscribed Angles
Students analyze inscribed angles and intercepted arcs and explore the relationships between the two. They investigate the properties of angles, arcs, chords, tangents, and secants to solve problems involving circles.
