Free SAT Lines, angles, and triangles Practice Questions
Lines, angles and triangles on the SAT covers parallel lines cut by a transversal, angle relationships, triangle properties, similarity, and coordinate-plane distance. Figures are often not to scale, so relationships must be derived rather than measured.

Preparing the question set…
Try three questions before signing in. Your first miss opens a hint; the full solution stays sealed until you solve or reveal it.
How the SAT tests lines, angles, and triangles
You apply angle rules, use similarity to set up proportions between corresponding sides, and compute distance and midpoint in the coordinate plane.
Where the points go
Pairing sides that do not correspond when triangles are drawn in different orientations, and trusting a figure drawn not to scale.
Every question you miss here is added to your mistake log with the specific error identified, and brought back after three days and again after fourteen — no screenshots, no error journal to keep.
