Learners calculate areas and lengths in triangles and quadrilaterals, using side lengths, angles, and the sine/cosine graphs of y = sin x and y = cos x. Tasks include identifying coordinates from graph sketches, adjusting graphs by vertical translation, and interpreting the effect of assuming an acute angle when finding triangle area.
