Problem 14 is causing problems on HW #9: connect from origin to A' to A and back. Is this an equilateral triangle? Now connect A' altitude to the X-axis. Does this new altitude divide the triangle into 2 30-60-90's? Take it from there. (Not on a quiz or test).
HW #9 - p 512:12,14, p 517:1-3,5,7. On the triangles in 5 & 7, you will need to use distance formula once for each side length.
- Apply Pythagorean Theorem to find missing side. (could be diagonal of a square or vice versa).
- Apply converse to determine if right, acute or obtuse.
- Use shortcuts to find missing sides of 30-60-90 or 45-45-90 (isosceles right). Might need to keep in radical form.
- Don't forget that equilateral triangle is just two 30-60-90
- Area of triangle or square or rectangle.
- Real world application of Pythagorean Theorem.
