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...
An obtuse angle is defined as an angle that is more than 90° but less than 180°. Obtuse Angle Degree In the above section, we read that an angle that measures less than 180 degrees and more than 90 degrees angle is called an obtuse angle. A few examples of obtuse angle degrees are...
