angle A = 45 deg
Special 45-45-90 deg triangles have sides in the
ratio of 1:1:(sqrt(2)) OR
ratio n : n : n(sqrt(2))
This means, in this problem,
side a = 1 (opposite side)
side b = 1 (adjacent side)
side c = 1*(sqrt(2)) (hypotenuse)
tan A = a/b = op/adj
tan 45 = ?
For acute angle Aof a right triangle, find tan A by using the 45-45-90 Triangle Theorem or the 30-60-90 Triangle Theorem.
