Regents Mathematics Algebra I Exam Objectives
As New York State transitions to the Common Core Learning Standards, the Integrated Algebra Exam becomes the Algebra I test. All high school students in the state must pass five subject-area tests, with scores of 65 or better, to earn the Regents Diploma.
This algebra test is composed of four parts, including concepts related to number and quantity, algebra, statistics and probability and functions. The questions are multiple-choice and free response, and you'll have three hours to complete the exam. Our short, multiple-choice quizzes can provide excellent practice for test day.
1. Points, Lines & Angles in Geometry
Geometry is a sector of mathematics that analyzes shapes, lines, and surfaces. Explore the definitions and examples of the basics of geometry: points, lines, and angles.
2. Types of Angles: Vertical, Corresponding, Alternate Interior & Others
Understanding angles and angle relationships allows for easier calculation of angle measurement. Learn how to define various types of angles, including vertical, corresponding, alternate interior angles, and how to calculate degree measurement using angle relationships.
3. Parallel, Perpendicular and Transverse Lines
Lines have a specific shape, but there are different types of them according to how they relate to other lines in the same plane. Learn about the different types of lines, including parallel, perpendicular, and transverse lines, and see the formulas you can use to determine the type of line.
4. Properties of Shapes: Rectangles, Squares and Rhombuses
Different objects come in different shapes that help achieve their purpose. Learn about the properties of different shapes, including rectangles, squares, and rhombuses.
5. Properties of Shapes: Quadrilaterals, Parallelograms, Trapezoids, Polygons
There are many different properties of shapes, but the perimeter of all of them is the sum of all its sides. Explore the properties of the more complicated shapes, including quadrilaterals, parallelograms, trapezoids, and polygons.
6. Properties of Shapes: Triangles
Triangles are three-sided shapes with three angles. Learn the basic properties of triangles, explore the types identified by their sides and angles and types classified by angles alone, and understand different combinations for naming triangles.
7. Properties of Shapes: Circles
In geometry, a circle is the round shape formed by the infinite set of points an equal distance from the center. Learn the definition of a circle, and explore its various parts and properties, including the radius, diameter, circumference, pi, and chord.
8. Perimeter of Triangles and Rectangles
Perimeter is defined as the combined distance around a shape, object, or figure, while the perimeter of any polygon can be determined by adding the length of all sides. Learn about perimeter, how to use mathematical formulas to calculate the perimeter of triangles and rectangles, and how to use perimeter to determine the length of unknown polygon sides.
9. Area of Triangles and Rectangles
The area of a two-dimensional shape represents the space covered within its perimeter, but area calculations change depending on the shape. Learn how to calculate and solve the areas of right triangles, oblique triangles, and rectangles.
10. Circles: Area and Circumference
Like all geometric shapes, circles take up space and a formula is required to calculate the area. Learn about the area and circumference of circles, explore the formula to calculate a circle's area, and review examples that use the diameter and others that use the circumference to find the area of a circle.
11. The Pythagorean Theorem: Practice and Application
Discover how the Pythagorean theorem helps people to solve for all sides of a triangle. Learn about the basics, purpose, and applications of the Pythagorean theorem.
12. How to Identify Similar Triangles
Similar triangles are defined as two triangles that possess proportional corresponding sides and congruent corresponding angles. Triangle similarity theorems use angle and side comparisons to determine whether two triangles are similar. Learn about the language of similarity, triangle similarity theorems (Angle-Angle, Side-Angle-Side, & Side-Side-Side), and how to use theorems to identify similar triangles.
13. Applications of Similar Triangles
Similar triangles have the same shape but differ in size. Learn about the applications of similar triangles, including how to use them and how to solve real-world problems with similar triangles.
14. Angles and Triangles: Practice Problems
When solving angles, they should be equal to each other or added together to equal 180, and with solving triangles, all angles in every triangle added together must equal 180 degrees. Engage in practice problems solving angles and triangles.
15. Vertical Angles & Complementary Angles: Definition & Examples
Vertical angles and complementary angles can be used to calculate unknown angle measurements. Learn the definition of vertical angles and review examples of how to use the properties of vertical angles and complementary angles to find the missing angle's measurements.
16. Overview of Three-dimensional Shapes in Geometry
Unlike two-dimensional shapes, three-dimensional shapes include a length, width, and height that give it depth. Explore the geometry of rectangular prisms, cubes, cylinders, spheres, and learn how to recognize examples of 3-D shapes in everyday objects.
17. How to Calculate the Volumes of Basic Shapes
The basic formula for volume is length * width * height and is necessary in geometry and the science of understanding mass in the form of basic shapes. Learn more about how to calculate the volumes of basic shapes and use the methodologies.
18. Volume of Cylinders, Cones, and Spheres
Volume is the capacity of an object or how much space something occupies in that object. Learn how to identify the volume formulas for cylinders, cones, and spheres, and discover why different shapes have different volumes that can be applied in real-world situations to calculate volume.
19. Volume of Prisms and Pyramids
The volume of prisms and pyramids can be calculated by multiplying the base and height and dividing the result by three. Learn more about the types of prisms and pyramids and how to calculate the volume of both.
20. Applying Scale Factors to Perimeter, Area, and Volume of Similar Figures
A scale factor is a number that shows the relationship between the corresponding perimeter, area, and volume of similar figures. Learn about the scale factor along with examples of how it is applied to perimeter, area, and volume.
