WebBy internal angle bisector theorem, the bisector of vertical angle of a triangle divides the base in the ratio of the other two sides. ( i ) A C A B = D C B D ∴ 4 . 2 5 = D C 2 . 5 WebArea of Equilateral Triangle $= \frac{\sqrt{3}a^2}{4} square units. Using Heron’s Formula. When the lengths of the three sides of the triangle are known, Heron’s formula is used to find the area of a triangle. Alt tags: An equilateral triangle with sides “a” units. Consider a triangle ABC with sides a, b, and c.

WebApr 11, 2024 · Hint: Use the Angle Bisector theorem, An angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of triangle. Here: \[\dfrac{BD}{DC}=\dfrac{AB}{AC}\] Angle bisector is a line which bisects the internal angle exactly by half. So from above figure we can say WebNov 14, 2024 · In Δ A B C, the bisector of the angle A meets the side BC at D and circumscribed circle at E, then DE equals to.
