The sum of the angles in a triangle equal 180°. abc is a triangle. angle a is > 90°. using deductive reasoning, what can we conclude?

We know that all triangles have a sum of 180 degree. If one angle of a triangle is greater than 90 degrees than we conclude that:

1. It is an obtuse triangle

2. It will have one obtuse angle(greater than 90 and two acute angles(less than 90))

2. It is not a right triangle(which has one angle of 90 degree)

3. It is not an equilateral triangle(in which all angles are equal)
