### Introduction to Coordinate Geometry

The students will use multiple representations of undefined terms on a coordinate plane to solve problems.

• Resource ID: GM4L3
• Subject: Math

### Determining Area: Sectors of Circles

Students will use proportional reasoning to develop formulas to determine the area of sectors of circles. Students will then solve problems involving the area of sectors of circles.

• Resource ID: GM1L18
• Subject: Math

Given conjectures about quadrilaterals, the student will use deductive reasoning and counterexamples to prove or disprove the conjectures.

• Resource ID: GM5L4
• Subject: Math

### Applying Trigonometric Ratios

Given problem situations involving similar figures, the student will apply and justify triangle similarity relationships such as trigonometric ratios.

• Resource ID: GM1L19
• Subject: Math

### Using Logical Reasoning to Prove Conjectures about Circles

Given conjectures about circles, the student will use deductive reasoning and counterexamples to prove or disprove the conjectures.

• Resource ID: GM3L8
• Subject: Math

### Coordinate Geometry: Special Segments

The student will derive and use the slope and midpoint formulas to verify geometric relationship that include parallelism and perpendicularity of lines. Then, the student will determine an equation of a line parallel or perpendicular to a given line.
