Key Curves in the June 2023 Geometry Regents
The Role of Circles in the Exam
Circles are fundamental in geometry, and the exam often emphasizes their properties.
Properties of Circles
- Equation of a circle: \((x - h)^2 + (y - k)^2 = r^2\), where \((h, k)\) is the center, and \(r\) is the radius.
- Tangent and chord properties: The tangent line is perpendicular to the radius at the point of contact.
- Arc and sector calculations: Lengths and areas involving parts of the circle.
Typical Problems
- Finding the equation of a circle given certain points or conditions.
- Determining the length of an arc or the measure of a central or inscribed angle.
- Solving for the points of tangency or intersection.
Parabolas: The U-shaped Curves
Parabolas are frequently tested in relation to their equations and properties.
Standard Forms and Key Features
- Equation: \(y = ax^2 + bx + c\) (quadratic form).
- Vertex form: \(y = a(x - h)^2 + k\), where \((h, k)\) is the vertex.
- Focus-directrix property: The parabola consists of points equidistant from the focus and directrix.
Exam-Relevant Concepts
- Identifying the vertex, axis of symmetry, and focus.
- Deriving the equation from given points or focus/directrix.
- Finding the equation of a parabola from its graph or key points.
- Applications involving parabola axes, vertex, and directrix.
Ellipses: The Oval-shaped Curves
Ellipses often appear in problem sets involving distances and ratios.
Equation and Properties
- Standard form: \(\frac{(x - h)^2}{a^2} + \frac{(y - k)^2}{b^2} = 1\).
- Foci: Two fixed points such that the sum of distances from any point on the ellipse to the foci is constant.
- Major and minor axes: The longest and shortest diameters.
Key Concepts Tested
- Finding the foci from the equation.
- Determining the lengths of axes.
- Using the foci property to solve geometric problems.
- Graphing ellipses from given parameters.
Hyperbolas: The Curves with Two Branches
Hyperbolas are less common but appear in advanced problem-solving.
Equation and Characteristics
- Standard form: \(\frac{(x - h)^2}{a^2} - \frac{(y - k)^2}{b^2} = 1\) (horizontal hyperbola).
- Foci and asymptotes: The hyperbola has two foci and asymptote lines guiding its shape.
- Branches: Two separate curves opening left/right or up/down.
Typical Problems
- Calculating the foci and asymptotes.
- Graphing hyperbolas based on equations.
- Solving for distances and intercepts related to hyperbolas.
