Make a hypothesis about the sum of all the angles in a trianglr.use the communication chcklist.
Hypothesis: The sum of all the angles in a triangle is always 180 degrees.
Communication Checklist:
1. State the hypothesis: The hypothesis is that the sum of all the angles in a triangle is always 180 degrees.
2. Justification: This hypothesis is supported by the fact that a triangle is a two-dimensional polygon with three sides and three angles. When the three angles of a triangle are added together, they always equal 180 degrees.
3. Prior knowledge: It is important to consider prior knowledge on geometric properties. In this case, the knowledge that a triangle has three sides and three angles, and that the sum of the interior angles of any polygon is (n-2) * 180 degrees (where n is the number of sides) can be used to support the hypothesis.
4. Prediction: Based on the hypothesis, we can predict that if we measure the angles of any triangle and add them together, the sum should always be equal to 180 degrees.
5. Test: To test the hypothesis, we can select a triangle and measure the angles using a protractor. By adding the measured angles together, we can determine if the sum is indeed 180 degrees or not.
6. Evaluation: After measuring and adding the angles, if the sum is equal to 180 degrees, the hypothesis is supported. If the sum differs from 180 degrees, the hypothesis is not supported.
7. Conclusion: Based on the results of the test, we can draw a conclusion regarding the validity of the hypothesis. If the hypothesis is supported, it can be considered as a reliable explanation for the sum of all the angles in a triangle being 180 degrees. If the hypothesis is not supported, further investigation may be necessary to explore the reasons behind the discrepancy.
