Mr. Cassidy introduces a lesson on angles and parallel lines, emphasizing the importance of a growth mindset and learning from mistakes. The lesson covers key concepts such as supplementary and vertical angles, parallel lines, and transversals. Students learn to identify and measure different types of angles formed by parallel lines and transversals, including interior, exterior, and corresponding angles. The lesson concludes with a reflection on the learning objectives.

Which of the following is NOT one of the core beliefs mentioned by Mr. Cassidy?

• Growth mindset matters

• Mistakes make the brain grow

• Effort is most important

• Speed is more important than accuracy
