#### Review Basics(03:46)

FREE PREVIEW

Review similar triangles and the angle-angle similarity postulate. Apply the theorem to determine the measurements of a triangle and examine a proof.

#### Right Triangles, Altitudes, the Pythagorean Theorem & You(07:31)

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.

#### Special Right Triangles(04:43)

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.

#### Units and Conversions(02:48)

Review standard units of measurement for English and Metric systems. Use ratios to convert yards to inches.

#### Perimeter(01:08)

Review definition of perimeter and how to find it for polygons.

#### Circleville(03:18)

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.
