In triangle abc angle a is obtuse
WebFeb 5, 2024 · is a quadratic in x; it will produce two solutions namely D E and D ′ E for the third side. The extra information that the third angle is obtuse pins down the unique triangle D E F ∼ A B C. Since D, D ′ must lie on either side of perpendicular dropped from F to B C, one of the two angles ( ∠ E D ′ F) is acute while other ( ∠ E D F ... WebFeb 2, 2024 · An exterior angle of a triangle is equal to the sum of the opposite interior angles. Every triangle has six exterior angles (two at each vertex are equal in measure). The exterior angles, taken one at each vertex, always sum up to 360 ° 360\degree 360°. An exterior angle is supplementary to its adjacent triangle interior angle.
