Lesson summary: The students will explore the similar right triangles and geometric mean relationships created when the altitude from the right angle to the hypotenuse of a right triangle is drawn. First the students determine what angles of the three triangles (the original right triangle, and the two on each side of the altitude) are congruent.

Motivation: We have found a link between the sides of a triangle (Pythagoras) and we know a link between the angles (they add to 180), so now we would like something which links the sides to the angles. Indirect Prerequisites: Scale factors, similar triangles, right-angled triangles.

3. Fill in the missing angles and side length K. Right triangles are triangles with one angle of 90 degrees. With right triangles (according to the Pythagorean Theorem) leg ² + leg ² = hypotenuse ² 7. Solve for the missing sides. With right triangles, we use sine, cosine, and tangent to help us find angle measures and side lengths.

Use trig ratios to find missing sides and angles of right triangles. Apply trigonometry to solve real-world problems. Use the Law of Sines to solve non-right triangles. Use the Law of Cosines to solve non-right triangles. Assignments: (not carved in stone but should give you an idea for planning purposes)
