Geometry Ace Lite vs Wave Simulator Lab by CS

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. Try before you buy! Full functionality for Points and Lines including transformations and constructions. Preview for Segments, Rays, Angles, Triangles, Quadrilaterals, Polygons, and Circles. Low cost in-app purchase upgrades to full function for all shapes. No ads! *** 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. • 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, finding slope, and writing 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: Note: LT version has full function for points and lines only. Other shapes are in preview mode. POINT: Coordinates Quadrants Distance between points LINE/RAY/SEGMENT: 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

Wave Simulator Lab is a beautifully designed, hands-on physics simulator for students, teachers, and curious learners. Slide the controls and instantly see how frequency, amplitude, and wavelength shape a wave — no math headaches, no equipment, just pure visual understanding. From a single sine wave to interference patterns, standing waves, damped oscillations, and real audible tones — every feature is paired with clear explanations, interactive controls, and ready-to-share visuals. Built for classrooms, study sessions, and after-school curiosity. WHY LEARNERS LOVE IT • See physics, don't just read it — every parameter updates the wave instantly • Friendly UI built for touch, with smooth animations at 60 fps • Clear, jargon-free explanations next to every concept • Quiz pack with answers explained, so mistakes turn into lessons • Designed for iPhone and iPad, light & dark mode supported FREE FEATURES • Real-time animated sine wave • Frequency, amplitude, and wavelength sliders • Automatic wave speed and period calculation • Play / pause / reset controls • Grid and axis toggles • Light, dark, and themed appearances • Basic learning library • Quiz pack with explanations UNLOCK ALL FEATURES (one-time purchase) • Remove all ads forever • All wave types — cosine, square, triangle, sawtooth, pulse, standing, damped • Compare two waves on one graph • Interference & superposition mode • Standing wave & damped wave modes • Sound wave tone generator (hear what you see) • Advanced measurement tools (ω, k, T, v) • Export wave images to share with classmates or teachers • Save unlimited custom presets • Full learn library + full quiz library • Extra themes (Space Wave, Graph Paper, and more) GREAT FOR • High school & university physics students • STEM teachers preparing live classroom demos • Homeschool families exploring science visually • Sound engineers and curious tinkerers • Anyone who wants to finally "get" waves NO SUBSCRIPTIONS.
