An isosceles triangle is a triangle in which two sides are equal in length. The angle between the two equal sides is called the vertex angle, while the other two are called the base angles. If the vertex angle is 40 degrees, what is the measure of the base angles?
If two sides of any triangle is equal, then their opposite angles are also equal.
The sum of the measures of all three angles in any triangle is 180˚
Let the base angle in degree be x. then other base angle also x.
The vertex angle is 40º . Then calculate the meas...
