Domain: Similarity, Right Triangles, & Trigonometry (GSRT)
Learning Standard: Understand similarity in terms of similarity transformations. Test Questions

GSRT0912.01 Verify experimentally the properties of dilations given by a center and a scale factor:

  • A dilation takes a line not passing through the center of the dilation to a parallel line, and leaves a line passing through the center unchanged.
  • The dilation of a line segment is longer or shorter in the ratio given by the scale factor.
22, 25
GSRT0912.02 Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar; explain using similarity transformations the meaning of similarity for triangles as the equality of all corresponding pairs of angles and the proportionality of all corresponding pairs of sides. 28, 29
Learning Standards: Prove theorems involving similarity. Test Questions
GSRT0912.05 Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures. 10, 17, 18
Learning Standards: Define trigonometric ratios and solve problems involving right triangles. Test Questions
GSRT0912.06 Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles. 1, 2, 3, 4
GSRT0912.08 Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems. 5, 6, 7, 8, 9
FR1
Domain: Circles (GC: GCA or GCB)
Learning Standard: Understand and apply theorems about circles. Test Questions
GCA0912.02 Identify and describe relationships among inscribed angles, radii, and chords. Include the relationship between central, inscribed, and circumscribed angles; inscribed angles on a diameter are right angles; the radius of a circle is perpendicular to the tangent where the radius intersects the circle. 31, 32, 34, 35, 38, 39, 40, 41
