leroyjenkens said:I was messing with the triangle on the interactive thing, and made the triangle just a line. It said the line is an obtuse isosceles triangle. Really? Is "obtuse isosceles triangle" really another way to say "a line"?
Edit: I was thinking about this and I think the definition of triangle should be (if it's not already) a shape with 3 angles, each greater than 0.

In geometry and trigonometry, diagrams are used to visually represent the given information and relationships between different elements. They help to make the proofs easier to understand and provide a visual aid for problem-solving.
When using diagrams in proofs, it is important to label all the elements accurately and clearly. Also, make sure to include all relevant information and use proper notation. You can also use different colors and shapes to highlight important elements and relationships.
No, diagrams should not be used as a substitute for written explanations in proofs. They serve as a helpful visual aid, but written explanations are still necessary to fully explain the reasoning and logic behind the proof.
One common mistake is not accurately representing the given information in the diagram. Another mistake is not using proper notation or labeling, which can lead to confusion or incorrect conclusions.
Practice is key to improving your skills in using diagrams for proofs. Make sure to regularly review and analyze diagrams from different proofs to better understand how they are used to represent relationships and information. You can also seek help from a tutor or teacher for additional guidance.
