This PowerPoint is designed to serve as guided notes to the first section in the chapter on similar figures. Vocabulary: similar polygons; similarity ratio (scale factor). Examples / guided practice problems include (7 problems in total): using the definition to determine similarity, writing a similarity statement, finding the similarity ratio, and using the definition to find a missing length, a missing angle or the value of a variable. Included are 2 PowerPoint files: 1. a student copy (can

This PowerPoint is designed to serve as guided notes to Similarity and Transformations section in the chapter on Similar Figures. This is a comprehensive guide to similarity and dilations. It takes students step by step through sketching or graphing figures using dilations with various centers. Vocabulary: dilation, center of dilation, scale factor, enlargement, reduction Concepts: - sketch an image with the given scale factor and the center of dilation; - graph an image with the given sc

This PowerPoint is designed to be used either in a physical classroom or in a Zoom (or other distance learning) classroom. This PowerPoint is intended to serve as a part of the unit on Polygon (including Triangle) Congruence. It contains guided notes, examples and practice problems. This lesson is designed to increase student class participation (including during distance learning) as each student’s active response is required for most problems. In a distance learning environment, this lesso

This PowerPoint is designed to be used either in a physical classroom or in a Zoom (or other distance learning) classroom. This lesson is a part of the unit on parallel lines. It includes the converses of theorems about angle pairs when two parallel lines are cut by a transversal. It contains guided notes, examples and practice problems. (You may purchase the previous lesson in this unit by clicking here, and download the next lesson for free by clicking here.) This lesson is designed to

This PowerPoint is designed to be used either in a physical classroom or in a Zoom (or other distance learning) classroom. This is the first lesson in the unit on parallel lines. It includes definitions of parallel, perpendicular and skew lines, parallel planes, and angle pair names when two lines are cut by a transversal. It contains guided notes, examples and practice problems. (You may purchase the next lesson in this unit by clicking here) This lesson is designed to increase student cla

This PowerPoint is designed with Zoom teaching in mind. However, it can be adopted for other distance learning platforms, as well as for teaching in the physical classroom (with some tweaks). This PowerPoint is designed to serve as a basic introduction to proofs. It contains guided notes, examples and practice problems. This lesson is suited for classrooms and students with average math skills as well as for struggling students, as most questions are multiple choice, and most proofs have s

This PowerPoint is designed to serve as an introduction to writing proofs. It contains guided notes, examples and practice problems. This product is editable - feel free customize it to fit the needs of your classroom! This product is geared towards stronger students, as it progresses quickly from fill-in-the-blank proofs to write-your-own proofs. If you are looking for a basic version geared towards weaker students, you may want to download it from my store here. (The basic version contain

This PowerPoint is designed to serve as guided notes to the Triangle Similarity section in the chapter on similar figures. AA Postulate SSS Theorem SAS Theorem Examples / guided practice problems include (11 problems in total, including 2 proofs): using AA, SSS, and SAS to determine triangle similarity, writing a similarity statement, and finding a missing side length or the value of a variable. Included are 2 PowerPoint files: 1. a student copy (can be used as a handout and/or a slide sho

This PowerPoint may be used either in a physical classroom or in a distance learning classroom. This is as a part of the unit on parallel lines. It includes theorems about angle pair relationships when two parallel lines are cut by a transversal. It contains guided notes, examples and practice problems.
