Sine Law (SSA)
(Ex 510X Q.6)
In triangle ABC, angle A = 45 degree, b = 4 cm, how many triangles can be formed and what is the possible value(s) of angle B if
(a) a = 2 cm?
(b) a = 2*sqrt(2) cm?
(c) a = 3 cm?
(d) a = 4.8 cm?
By dragging point B. Try to find out the answer and understand why sometimes 2 triangles are formed and sometimes no triangles are formed.
