WebAnswer (1 of 2): I assume you’re talking about how the sum of the angles of a triangle add up to 180 and that the audience is kids in the 10–12 year range. I would teach it by demonstration of the limits of a triangle. First, I’d talk about a triangle with side lengths 5, 5, and 10. We’d try to ... WebOct 11, 2024 · We also know that a triangle adds up to be 180 degrees and that our figure in the center is a triangle. So: $180 - 80 - 50 = 50$ degrees. This means that the missing value in our triangle is also 50 degrees. Again, we know that opposite angles equal one another, so the angle opposite this 50 degrees will also be 50 degrees.
WebAngles On One Side of A Straight Line. Angles on one side of a straight line always add to 180 degrees. Example: 30° + 150° = 180°. When a line is split into 2 and we know one angle, we can always find the other one. WebAngles, Triangles.
