Triangle ABC is shown below. Contact. On signing up you are confirming that you have read and agree to AB2 = 2AC2 If BC = 10x-4 , AC= 2x+18 , and AB= 6x+32, find the value of x. Geometry. Show that BC is tangent to O Use this to show that ZCMB= ZCBM . ∠ BCD = (180°)/2 = (AC)2 + (AC)2 (Given AC = BC) i.e. = AB2 Side BA is produced to D such that AD = AB (see the given figure). Show that (i) ABE ≅ ACF (ii) AB = AC, i.e., ABC is an isosceles triangle. Triangle ABC and triangle BDE are two equilateral triangle such that D is the midpoint of BC find the ratio of their areas of triangle ABC and triangle BDE? c. 14. In ΔABC, let the altitude AD bisects ∠BAC. Therefore, ABC is an isosceles triangle in which AB = AC. 7.15). The figure shows an isosceles triangle ABC with
