WebMath Geometry C is the incenter of isosceles triangle ABD with vertex angle ZABD. Does the following proof correctly justify that triangles ABC and DBC are congruent? 1. It is given that C is the incenter of triangle ABD, so segment BC is an altitude of angle ABD. 2. Angles ABC and DBC are congruent according to the definition of an angle bisector. WebFeb 2, 2024 · To calculate the isosceles triangle area, you can use many different formulas. The most popular ones are the equations: Given leg a and base b: area = (1/4) × b × √ ( 4 × a² - b² ) Given h height from apex and base b or h2 height from the other two vertices and leg a: area = 0.5 × h × b = 0.5 × h2 × a.
