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.

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 question quiz, fill in the blank and solving for x/y.

Basic Angle Addition Postulate and notation/parts of angles. 3 versions with keys - this was created with Pearson TestGen software using my own personal testbank

3 versions with keys - Versions A+B are similar and easy. Version C is challenging. All worksheets were created with Pearson TestGen software using my own personal testbank

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.

A short pre-proof activity that uses algebra to begin the concept of proving using statements and reasons. This was made in Microsoft 2013 and converted to PDF. Key included

This activity practices finding equations of lines using point-slope or slope-intercept. Includes an answer bank with all potential answers plus a few extra. Includes a key with all potential answers. This is a great differentiated activity to sum up equations of lines while allowing flexibility for students to pick the method (point-slope or slope-intercept) with which they are most comfortable!

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 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).

One quiz on concepts relating to proving lines are parallel Another quiz on algebraically solving to make the lines parallel Both include keys

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.
