Domain - Similarity, Right Triangles, and Trigonometry

Cluster - Define trigonometric ratios and solve problems involving right triangles.

[GEO.G-SRT.C.8] - Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.*

Resources:


  • Pythagorean Theorem
    For any right triangle, the sum of the squares of the measures of the legs equals the square of the measure of the hypotenuse.
  • Ratio
    A relationship between quantities such that for every a units of one quantity there are b units of the other. A ratio is often denoted by a:b and read “a to b”.

Predecessor Standards:

  • 8.G.B.7
    Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions.

Successor Standards:

No Successor Standards found.

Same Level Standards:

  • GEO.G-SRT.C.6
    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.
  • GEO.G-SRT.C.7
    Explain and use the relationship between the sine and cosine of complementary angles.
  • GEO.G-SRT.D.10
    (+) Prove the Laws of Sines and Cosines and use them to solve problems.
  • GEO.G-SRT.D.11
    (+) Understand and apply the Law of Sines and the Law of Cosines to find unknown measurements in right and non-right triangles (e.g., surveying problems, resultant forces).
