FAQs

What transformations are covered in the EOC Review 2018 Key?
The EOC Review 2018 Key covers various transformations including translations, dilations, reflections, and rotations. Each transformation is described with specific rules and examples, such as translating points by certain rules or reflecting over lines like y = x and y = -3. The document also includes tasks related to rotating figures 90 degrees clockwise and counterclockwise, as well as finding new coordinates after dilations.
How do you find the coordinates after a dilation by a factor of 5?
To find the coordinates after a dilation by a factor of 5, you multiply each coordinate of the original points by 5. For example, if you have a point S with coordinates (-5, 2), after dilation, the new coordinates would be (-5 * 5, 2 * 5), resulting in (-25, 10). The document provides specific examples for points S, Y, R, and A, illustrating how to apply this factor to obtain new coordinates.
What methods are used to determine angle measures in triangles?
The document discusses several methods for determining angle measures in triangles, including using properties of supplementary and complementary angles, as well as vertical angles. It emphasizes the importance of knowing that the sum of angles in a triangle equals 180 degrees. Additionally, it provides examples of solving for angles using given measures and relationships between angles, such as alternate interior angles and corresponding angles.
What is the significance of the Pythagorean Theorem in the review?
The Pythagorean Theorem is highlighted as a critical concept in the EOC Review 2018 Key, particularly in the context of right triangles. It states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. The document provides examples of how to apply this theorem to find missing side lengths and to solve real-world problems involving right triangles.
How are congruent triangles identified in the study guide?
Congruent triangles are identified using several criteria outlined in the document, including SSS (Side-Side-Side), SAS (Side-Angle-Side), and ASA (Angle-Side-Angle). The document explains that if two triangles can be shown to have corresponding sides and angles that are equal, they are congruent. Specific examples illustrate how to apply these criteria to determine triangle congruence in various geometric scenarios.
What types of symmetry are explored in the EOC Review?
The EOC Review explores various types of symmetry, including rotational symmetry and reflectional symmetry. For instance, it discusses which shapes exhibit 90-degree rotational symmetry, such as squares and regular hexagons. The document also includes tasks that require identifying lines of symmetry and determining how shapes can be mapped onto themselves through these symmetries.
What is the formula for the area and circumference of a circle mentioned in the review?
The document provides the formulas for calculating the area and circumference of a circle. The area is calculated using the formula A = πr², where r is the radius of the circle. The circumference is calculated using the formula C = 2πr. These formulas are essential for solving problems related to circles in the geometry section of the review.
