How do you know if a triangle is obtuse
Did you know?
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. WebObtuse Triangles. An obtuse triangle has one obtuse angle (i.e. greater than 90°). The longest side is always opposite the obtuse angle. In the obtuse triangle shown below, a is the obtuse angle. Since the sum of all the …
