Review similar triangles and the angle-angle similarity postulate. Apply the theorem to determine the measurements of a triangle and examine a proof.
Use an altitude to make any triangle a right triangle; see a theorem proving the similarity of two triangles within a right triangle. Learn the Pythagorean theorem and use it to determine the hypotenuse of right triangles.
The two special right triangles are 45-45-90 and 30-60-90. Use these two theorems to determine the hypotenuse of triangles. Review similarity and the angle-angle similarity postulate.
Review standard units of measurement for English and Metric systems. Use ratios to convert yards to inches.
Review definition of perimeter and how to find it for polygons.
Learn the definition of a circle and its components. Use two formulas to find the circumference of a circle: C = pi * d and C = pi * 2r.
