About this ebook
The 2nd Edition of Geometry by Elayn Martin-Gay, published by Pearson, provides a comprehensive foundation in Euclidean geometry. It focuses heavily on geometric reasoning, active learning, and real-world applications. [1, 2, 3]
Core Topics Covered
The textbook structures its chapters around the following core mathematical concepts: [1]
- Foundations of Geometry: Reasoning, conditional statements, mathematical logic, formal proofs, and structured problem-solving.
- Lines and Angles: Angle relationships, parallel lines, and perpendicular lines.
- Transformations & Coordinates: Transformations (reflections, rotations, translations), coordinate geometry, and geometric constructions.
- Polygons & Triangles: Properties of triangles, congruence theorems, and properties of quadrilaterals.
- Similarity: Similarity transformations, proportions, and scale factors.
- Right Triangles & Trigonometry: The Pythagorean theorem, special right triangles, and basic right-triangle trigonometry.
- Circles: Properties of circles, chords, tangents, secants, arcs, and conic sections.
- Measurement & Dimension: Measuring area, surface area, and volume for 2D and 3D geometric shapes.
New and Updated Objectives in the 2nd Edition
The 2nd Edition explicitly introduces fresh instructional objectives to match updated classroom standards: [1]
- Portion a Direct Line Segment: Partitioning a segment into given ratios.
- Determine Similarity Transformations: Identifying and mapping geometric similarity through dilations and rigid motions. [1]
