isosceles triangle A triangle with two equal sides,hence its base angles are also equal. The triangle has anaxis of symmetry which is an altitude of the triangle. 相关知识点: 试题来源: 解析 等腰三角形两边相等的三角形,因而其底角也相等.这种三角形有一条高是三角形的对称轴 反馈 收藏 ...
An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length b and the remaining side has length a. This property is equivalent to two angles of the triangle being equal. An isosceles triangle

In an obtuse angled scalene triangle, there is one obtuse angle (between 90° and 180°) and remaining two angles are acute.Right-angled scalene triangle In a right-angled scalene triangle, one angle of the triangle is a right angle (one angle is equal to 90°)....
The cos formula can be used to find the ratios of the half angles in terms of the sides of the triangle and these are often used for the solution of triangles, being easier to handle than the cos formula when all three sides are given. but Let or where is the semi perimeter of...
