Geometry Concepts vs Geometry Ace

Geometry Concepts is an interactive learning system designed to provide instruction in mathematics at 7th grade through adult levels. The instructional goals for Geometry Concepts include several objectives. The primary objective for this app is to provide basic information about geometry through interactive lessons. Tap the notebook icon open dynamically illustrated lessons on each of the seven topics: Basic Concepts, Circles, Angles and Triangles, Lines and Planes, Area and Perimeter, 2-Dimensional Figures and 3-Dimensional Figures. Our goal in designing this app is to incrementally build an understanding of fundamental concepts by providing an easy-to-use format for exploring geometry. Tap the magnifying glass icon to explore a topic more deeply. Each of the images are interactive. Tap to reveal terms and key concepts. Tap the more info icon for detailed information about the highlighted term. We hope to support the development of a sense of confidence in each user's mathematical ability through a variety of educational approaches. Geometry Concepts includes a reference system, lessons, randomly generated quiz questions and an exploratory tool for open-ended investigations. Tap the tool icon on the main navigation screen to access a set of 12 interactive tools for exploring geometry concepts. Icons on the sides of the screen are used to change the investigation. Manipulated the tools to learn more about each concept. We think your students will enjoy learning with Geometry Concepts.

Geometry Ace is a fusion between a graphics based calculator and a geometry textbook. Detailed step-by-step solutions update as you create new math problems by changing the graphics. Learn vocabulary with unlimited examples. Points, Lines, Segments, Rays, Angles, Triangles, Quadrilaterals, Polygons, and Circles. Transformations and Constructions. Full functionality with no ads or in-app purchases. Great classroom or home resource for elementary, middle, and high school students and teachers. *** Easy Start-up *** • Simply choose shape to study. • Shape will already be on the screen and all you have to do is start manipulating it. • Learn vocabulary, choose from list of tutorials, perform transformations, or create a construction. *** Detailed problem solutions update as you change the graphics. *** • You are not limited to a set of pre-written or randomly generated problems. • Tutorial examples: finding the length of a line segment, finding the area of any type of quadrilateral, calculating the length of an arc, and many more. • Geometry Ace does not simply calculate lengths and areas for you. It shows you step-by-step how to do it! *** Includes introductory material and makes connections with algebra. *** • Introductory material appropriate for upper elementary students is included. • Helps with differentiation. Middle and high school students who need a refresher can review introductory topics. • Algebra topics needed for coordinate geometry are included. • Introductory topics include coordinates of a point, slope, and the equation of a line. • Answers to problems are given in fraction form when possible. • Solutions address common student misconceptions and give attention to detail. *** Interactive definitions *** • Relevant definitions highlight interactively as you drag points and lines to change the shape on the screen to meet various attributes. • Example: A triangle can be obtuse, oblique, and scalene. • Example: A polygon can be concave and irregular. • Definitions are inclusive. Example: A quadrilateral that is a rectangle is also a parallelogram and a trapezoid. *** Transformations: Rotations, Reflections, and Translations *** • Easily change degrees of rotation, center of rotation, line of reflection, and translation vector. • Point mapping is shown! • Perform successive transformations on the same object. *** Constructions *** • Includes points, lines, segments, circles, perpendicular lines, parallel lines, tangents, and angle bisectors. • Easily make attachments to points, lines, circles, intersections, and midpoints. *** Monitor Students *** • Teachers can view student’s iPad screens who are on the same local wifi network and running this app. TOPICS AVAILABLE IN GEOMETRY ACE POINT: Coordinates Quadrants Distance between points LINE/RAY/SEMGENT: Slope Vertical, Horizontal Y-intercept Equation of line/ray/segment Distance between point and line Construct or write equation of parallel or perpendicular line Segment midpoint and length Construct or write equation of perpendicular bisector Intersection point of 2 lines Transversals Alternate interior angles Alternate exterior angles Corresponding angles Same side interior angles Vertical angles ANGLE: Vertex, Legs, Interior, Measure Acute, Right, Obtuse, Straight, Reflex Convert between degrees/radians Construct or write equation for angle bisector Congruent, Adjacent, Complimentary, Supplementary, Linear Pair, Vertical TRIANGLE: Acute, Obtuse, Right, Oblique, Equilateral, Isosceles, Scalene Perimeter Area – basic elementary Area – coordinate plane - algebra Area – box method Centroid, Circumcenter, Incenter QUADRILATERAL: Square, Rectangle, Rhombus, Parallelogram, Trapezoid, Kite Perimeter Area POLYGON: Triangle, Quadrilateral, Pentagon, Hexagon, Heptagon, Octagon, Nonagon, Decagon Convex, Concave Regular, Irregular Sum of interior angles CIRCLE: Radius, Diameter, Tangent, Secant, Chord Circumference Area Measure and length of an arc Area of a sector
