Question
Write the sum of the angles of an obtuse triangle.
Advertisements
Solution
In the given problem, ΔABC is an obtuse triangle, with ∠B as the obtuse angle.
So, according to “the angle sum property of the triangle”, for any kind of triangle, the sum of its angles is 180°. So,
∠A+ ∠B + ∠C = 180°
Therefore, sum of the angles of an obtuse triangle is 180°.
