C-09-Q025mediumsingle_mcq

In similar right-angled triangles, the ratios of sides corresponding to a fixed acute angle are—

avariable
bconstant
calways $1$
dalways $0$

ব্যাখ্যা

Because the triangles are similar, corresponding sides are proportional, so for a fixed acute angle the ratio of any two corresponding sides stays the same regardless of triangle size. This invariance is the foundation on which trigonometric ratios are defined.
