Geometry Mathematics Standards: Right Triangles

Special Right Triangles & Pythagorean Theorem - Students explore right triangles and apply the Pythagorean Theorem.

G.RT.1

Not covered
Apply the properties of special right triangles (30°-60°-90° and 45°-45°-90°) to solve real-world and mathematical problems.
(Content unavailable)

G.RT.2

Mostly covered
Prove and apply the Pythagorean Theorem and its converse.

Trigonometry Ratios - Students apply trigonometric ratios to solve problems.

G.RT.3

Mostly covered
Explain how the definitions for trigonometric ratios are developed by similarity and how the side ratios in right triangles are properties of the angles in the triangle.

G.RT.4

Mostly covered
Explain the relationship between the sine and cosine of complementary angles and use them to solve problems.

G.RT.5

Partially covered
Determine the sine, cosine, and tangent ratios of acute angles given the side lengths of right triangles.

G.RT.6

Partially covered
Use trigonometric ratios (sine, cosine, and tangent) to calculate missing side lengths and angle measures in a right triangle, including applications of angles of elevation and depression; include real-world and mathematical problems.
