Question
I draw an obtuse, isosceles triangle with one of the angles measuring 25 degrees, what is the measure of the obtuse angle?
Solution
In an isosceles triangle, the base angles (the angles that are the same) are equal. If one of the base angles is 25 degrees, then the other base angle is also 25 degrees.
To find the measure of the obtuse angle, we subtract the sum of the base angles from 180 degrees (since the sum of all angles in a triangle is 180 degrees).
So, the calculation would be:
180 degrees - 25 degrees - 25 degrees = 130 degrees
Therefore, the measure of the obtuse angle in the triangle is 130 degrees.
