As shown in the figure: in △ ABC, ∠ C = 90 ° ad bisection ∠ cab intersects BC at point D, ab = 10, AC = 6, find the distance from D to ab

As shown in the figure: in △ ABC, ∠ C = 90 ° ad bisection ∠ cab intersects BC at point D, ab = 10, AC = 6, find the distance from D to ab

Let de ⊥ AB, e be the perpendicular foot, and de be the distance from D to ab. in △ ABC, ⊥ C = 90 °, ab = 10, ⊥ AC = 6, ⊥ BC = 8, let CD = x, then de = CD = x, BD = 8-x. in RT △ ACD and RT △ AED, ⊥ CD = edad = ad, ≌ RT △ ACD ≌ RT △ AED
