The Pythagorean theorem states that for any right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. It can be written as a2 + b2 = c2, where c is the hypotenuse and a and b are the other two sides. The distance formula calculates the distance between two points (x1, y1) and (x2, y2) on a coordinate plane as √(x2 - x1)2 + (y2 - y1)2. For example, the distance between points (4,3) and (-5,8) using the distance formula is 10.29.

Frequency tables and line plots
When the items being tallied are numbers, a line plot can be used to visually display numerical data. A line plot uses X marks above a number line to show the frequencies. For example, a line plot of the number of books students read shows the frequencies of students who read 1 book, 2 books, and so on up to 7 books.
A frequency table organizes categorical data into categories and displays the frequency of each category. For example, a frequency table asking students' favorite color would have categories for different colors and show how many students chose each color. Analyzing frequency tables and line plots can identify outliers, clusters, or gaps in the data distributions.

1.8 lab
This document contains instructions for an experiment to measure the time it takes for a varying number of students to complete a task of standing, clapping, and sitting. Students will take turns performing the task until all have participated, and the time to complete each round will be recorded. The number of students is the independent variable and time is the dependent variable. Data for groups of 3 to 24 students will be plotted on a graph and the best fit line drawn to analyze the correlation between more students and longer completion times.
Budget project
This document provides instructions for creating a realistic monthly budget. It explains that a budget accounts for income versus expenses, with the goal of expenses being less than income. Common expenses are listed like housing, utilities, transportation, food, and savings, which should be at least 5% of income. Students will be assigned an occupation with a set income and must choose housing, a car, and estimate other expenses to track in a monthly budget worksheet. If expenses exceed income or savings is less than 5%, spending habits must be adjusted.
Scale drawing table
This document provides instructions for creating a scale drawing of a piece of furniture. It notes that measurements should be provided in either boxes or inches, not both. As an example, a grey shelf that is 3 feet by 1 foot in real life would be drawn as either 3 boxes by 1 box or 0.75 inches by 0.25 inches on the scale drawing, since the scale factor is that 1 foot equals 1/4 inch or one box.
Linear equation graphic
A linear equation is represented by y = mx + b, where m is the coefficient that determines the steepness of the graph line, b is the y-intercept or the point at which the line crosses the y-axis, and x and y are coordinate pairs that each represent a single point on the line.
Slope
This document discusses the slope formula for a line, which is the ratio of the rise over the run between any two points on the line. Specifically, it notes that the slope (m) equals the rise over the run, where the rise is the change in the y-values and the run is the change in the x-values between the two points.
Scale drawing project
This document provides instructions for a scale drawing project of a classroom floor plan. Students are asked to measure a classroom, determine an appropriate scale to fit the room on a piece of graph paper, and draw the outline of the room along with major furniture items using the scale. Students must include a scale bar, title, and colors to make the floor plan realistic. The project aims to provide floor plans of classrooms to facilitate school renovations.
Scale drawing do nows
Jenn had to create a scale drawing of her classroom for a school project. She measured her classroom and found it was 24 feet by 30 feet. To fit the drawing on graph paper, Jenn decided to use a scale of 1 foot equals 1/4 inch.
Lifeline project grade sheet (2)
This grade sheet is for a lifeline project and assigns points to students for correctly graphing life events before and after their birth on a timeline, using accurate numerical representations and year intervals, as well as adding illustrations or labels for graphed events. It outlines the specific criteria students will be judged on, including correctly placing their birth at zero, graphing at least three pre-birth and six post-birth events, and creating a neat and creative final project.
Lifelineproject
This document provides directions for creating a personal lifeline. Students must include their birth and at least 3 events that occurred before they were born, with each event listing the date as a fraction of years before or after the student's birth (assigned as 0). Events should have the month and year, the student's age at the event, and a brief description. Sample events include parents meeting, siblings being born, first teeth, words, bike riding, moves, vacations, or historical events. The lifeline may include one break and some photos.
L4 angles in polygons
The document provides examples and explanations of geometry concepts including finding the perimeter of a regular octagon where one side is 12 cm, the triangle sum rule stating the interior angles of a triangle sum to 180 degrees, the definition of a diagonal as a line segment connecting two non-adjacent vertices of a polygon, and examples of finding the number of diagonals in nonagons and dodecagons.
Congruent angles go
Vertical angles are angles that are opposite each other when two lines intersect. Corresponding angles are angles that are in the same relative position to the point of intersection but on opposite sides of the intersecting lines. Alternate exterior angles are nonadjacent angles outside of the intersecting lines formed by a transversal crossing two parallel lines. Alternate interior angles are nonadjacent angles inside of the intersecting lines formed by a transversal crossing two parallel lines.
Lesson 3 line and angle relationships
This document discusses different types of lines and their relationships. It defines parallel lines as two lines that lie in the same plane and do not intersect, intersecting lines as lines that cross paths at one point, and skew lines as lines that do not lie in the same plane and neither intersect nor are parallel. The document also notes that two points are needed to form a line and that two straight lines cannot intersect at more than one point.
Angle relationships
1) The document defines and provides examples of different types of angles including adjacent angles, complementary angles, supplementary angles, vertical angles, and angles formed when parallel lines are cut by a transversal.
2) It then provides practice problems involving calculating missing angles using properties such as angles summing to 90 or 180 degrees. Problems include solving for missing angles in triangles where the three interior angles sum to 180 degrees.
3) The last problems involve identifying properties of angles formed when two lines are parallel and cut by a transversal, such as naming congruent or supplementary angles.
Building blocks of geometry
The document defines basic geometry terms including point, line, plane, ray, line segment, and angle. A point is represented by a dot at a location without size. A line extends in two opposite directions and is named by two points. A plane extends forever like a tabletop. A ray has one endpoint and extends forever in one direction, while a line segment connects two endpoints on a line.
Sample questions 2013
The document contains 4 math word problems and their solutions:
1) Choosing 2 students from a group of 4 can be done in 6 combinations.

3) A room measuring 8 feet 6 inches by 12 feet with 6-inch tiles needs 408 tiles.
4) A sequence with first terms 3, 5, 7, 9 has a rule of adding 2 to get the next term; a different sequence following the same rule of adding 2 would have first terms 5, 7, 9, 11, and the 100th term would be 198.
