20 good questions about - naming corresponding parts of similar polygons - setting up proper proportions of sides of similar polygons - determining whether polygons are similar based on angles and side lengths - writing proper similarity statements - solving for variables using similar polygons - working with ratios and proportions to solve real problems This worksheet is ideal for beginning a chapter on polygon similarity, before the triangle theorems are introduced.

- Triangle Inequality Theorem - One-Triangle Inequalitites - Two-Triangle Inequalities (SAS Inequality and SSS Inequality) - Properties of Inequalities - Indirect Proof - Inverse and Contrapositive all in an easy to edit Microsoft Word file

Calculating distance between points and using it to prove isosceles, scalene, or equilateral triangles, congruent segments, or perimeter of a figure. Included: A 16 problem Worksheet An 8 problem Homework Two versions of a short quiz/exit ticket - 2 questions calculating perimeter and finding out whether segments are congruent using distance formula Answer keys included

Proving triangles congruent using SSS, SAS, and ASA Postulates. 5 fill in the blank proofs and 5 full proofs with key. Parallel lines, definition of midpoint and angle bisector, etc. mixed with triangles. Great proof practice.

Perfect Worksheet for naming corresponding sides, angles, and triangles in corresponding order. Includes algebra and coordinate problems. This is a good length for a homework assignment or assessment after the lesson.

11 good fill in the blank proofs + KEY Uses definitions and theorems related to: congruence right angles perpendicular lines vertical angles complementary angles supplementary angles midpoint angle bisector and properties of equality and congruence

22 matching sine/cosine graphs (excluding horizontal shift) with 4 extra graphs thrown into the answer bank. Key included. All graphs were computer generated and adjusted to be easy to read for students.

This handout teaches the basics of finding the volume of prisms.

Geometry Angles and Arcs Circle Quiz: Quiz covers all angles and arcs that can occur within circles. 8 problems, with high quality pictures. Key included. (can be used as homework)

This quiz is fill in the blank terms from circles, including segments, lines, angles, and arcs. Key included.

This practices all types of problems that use law of sines and law of cosines. Answers included.

This worksheet teaches how to convert polar equations of lines and circles to rectangular form and graph. There is a review of some identities and completing the square and a few lists of important formulas. Key included.

This worksheet teachers the basics of graphing polar coordinates, using polar graphs. It is step by step and includes a bonus page of blank polar graphs for use in class.

This worksheet uses the sum/difference identities with inverse trig functions. This is a great way to review inverse (sin-1 cos-1 tan-1) trig functions and combine with the sum and difference identities. The first problem is completely worked out and explained with a diagram. Then three additional problems for the students to work out follow. Last page is the answer to the student problems.

Quiz has 3 solve for x/y angles/sides problems and 1 word problem. Utilises isosceles triangle theorems as well (for review).

This is a great "real life" example using piecewise functions. Students learn the basics of tax brackets and can calculate basic tax owed by using piecewise functions. It is very thorough and includes some practice problems and answers. Highly challenging for an Algebra II or PreCalculus class.

This quiz is fill in the blank for two difficult proofs using theorems/definitions of perpendicular lines. Can be edited as a practice assessment/homework or given as a quiz. All pictures are high quality and made on Geometer's Sketchpad. Key included for both proofs.

This is a true/false quiz testing understanding, not just memorization, of the initial postulates and theorems. Attached is the answer key.
