C-10-Q160mediumsingle_mcq

Trigonometric ratios are independent of the size of a right triangle because of the—

aadditive property
bsimilarity of triangles
cPythagorean theorem
dparallel-line theorem

ব্যাখ্যা

For a given acute angle, all right triangles are similar, so the ratios of corresponding sides stay constant regardless of the triangle's size. This similarity is exactly why each trigonometric ratio depends only on the angle.
