百度试题 结果1 题目1. Do you know what degrees the angles(angle) of a triangle are? 相关知识点: 试题来源: 解析 答案见上III.1.angles 考查名词复数。分析句子,由degrees和 are可知设空处需要填名词的复数形式,故填 angles。 反馈 收藏
A. **180度**:正确。这是三角形的基本性质,可通过平行线定理或拼接法证明。 B. 360度:错误。360度通常是四边形的内角和(如矩形)。 C. 90度:错误。单个直角为90度,但三个内角总和需更大。 D. 120度:错误。仅当三个内角均相等时(如等边三角形),每个角为60度,总和仍然为180度。 因此,正确答案为A。
