3. Sum of Angles in a Triangle: We know that the sum of all angles in a triangle is always 180∘. Thus, we can write: ∠A+∠B+∠C=180∘ Hint: Use the property that the sum of angles in a triangle is 180∘. 4. Substituting Equal Angles: Since all angles are equal, we ...
The sum of the measures of all the angles of a triangle is( ).A.180∘B.120∘C.90
A. 90 degrees B. 180 degrees C. 270 degrees D. 360 degrees 相关知识点: 试题来源: 解析 B。本题涉及数学中的三角形角度知识。选项 B“180 degrees”,三角形内角和始终为 180 度。选项 A“90 degrees”是直角的度数。选项 C“270 degrees”和选项 D“360 degrees”都不符合三角形内角和。反馈...
