The base is the unequal side, and the angles adjacent to it are the base angles. 33 degrees, and the vertex angle is 73.
Steps to Find Base Angles Isosceles Triangle
Identifying the Base Correctly A common point of confusion is determining which side is the base. For example, if the vertex angle is 40 degrees, the base angles sum to 140 degrees.
These matching sides create congruent angles opposite them, which are the base angles. Because the triangle is isosceles, the base angles are equal, making the math straightforward.
Steps to Find Base Angles Isosceles Triangle
Since the two base angles share this value equally, dividing 72 by 2 results in 36 degrees. This method is reliable for any isosceles triangle as long as the vertex angle is provided.
