Drag and drop an answer to each box to derive a formula for the area of the triangle 2
С
Because two points determine a line, you can draw altitude BD perpendicular to AC, which has height h By the definition of a
sine ratio,
which can be rearranged intoa sin C = h. The formula for the area of a triangle is
Area = bh. Use the substitution property of equality to get
which rearranges into
by the commutative property of multiplication
