**pp. 426-429** - Scale Drawings

**pp. 301-302** - Constructing Perpendicular Lines

**pp. 311-312** - Constructing Angle Bisectors and Segments

**pp. 343** - Pythagorean Theorem

**pp. 344-350** - The Pythagorean Theorem

*Alignment to CA Mathematics Standards:*

**Measurement and Geometry**

1.2 construct and read scale drawings and models

3.1 identify and construct basic elements of geometric figures, (e.g., altitudes,
midpoints, diagonals, angle bisectors and perpendicular bisectors; and central angles,
radii, diameters and chords of circles) using compass and straight-edge

3.3 know and understand the Pythagorean Theorem and use it to find the length of the
missing side of a right triangle and lengths of other line segments, and, in some
situations, empirically verify the Pythagorean Theorem by direct measurement

**Mathematical Reasoning**

1.1 analyze problems by identifying relationships, discriminating relevant from irrelevant information, identifying missing information, sequencing and prioritizing information, and observing patterns

1.2 formulate and justify mathematical conjectures based upon a general description of the mathematical question or problem posed

2.4 make and test conjectures using both inductive and deductive reasoning

2.7 indicate the relative advantages of exact and approximate solutions to problems and give answers to a specified degree of accuracy

**Resources**

**Assessment**
- Students will demonstrate understanding of increases and decreases.
- Students will solve problems that involve discounts, markups, commissions, profit and simple
compound interest with decimals and money.
