How do you know if a triangle is obtuse
WebAn obtuse triangle has only one angle greater than 90° since the sum of the angles in any triangle is 180°. If one of the angles is greater than 90°, then the sum of the other two angles must be less than 90°, so the other two angles must both be acute angles. For DEF above, ∠D + ∠F = 60° < 90°, so ∠D and ∠F are acute angles. WebWhat I want to do in this video is talk about the two main ways that triangles are categorized. The first way is based on whether or not the triangle has equal sides, or at least a few equal sides. Then the other way is based on the measure of the angles of the triangle.
