解析 C。本题考查三角形的概念。有一个角是 90 度的三角形是直角三角形,right triangle 表示直角三角形,所以选 C 选项。A 选项 equilateral triangle 是等边三角形。B 选项 isosceles triangle 是等腰三角形。D 选项 scalene triangle 是不等边三角形。
Now we know the measure of two angles are 39∘ and 69∘. By the Triangle Sum Theorem, the sum of all angles in a triangle is 180∘, so the final angle is 72∘ . Therefore, the largest angle in the triangle is (B) 72.反馈...
直角三角形 (Right Triangle):有一个内角为直角。 钝角三角形 (Obtuse Triangle):有一个内角为钝角。 2. 四边形的角 (Angles in Quadrilaterals) 四边形的内角和为360度。根据不同的性质,四边形可以分为: 矩形(Rectangle):四个内角均为直角。 平行四边形 (Parallelogram):对角相等且相邻角互补。
