Euclidea vs Geometry

Euclidea: Sketches is an interactive geometry app intended for creating and exploring geometrical constructions. It is a great companion for the classic Euclidea Puzzles app. You start with an empty board and create your sketch with just a few taps. > Use smart and powerful tools > Choose shapes from a template library > Explore your constructions: they can be changed dynamically > Customize your drawing > Label points > Organize you own drawing collection > Export to photo album ***For Euclidea Puzzles users*** The app is much more than a sandbox for Euclidea. The tools were revised and significantly improved. Since you do not need to count moves anymore, the same constructions can be reproduced faster. ***How to use*** There are 4 modes: Constructing, Decorating, Coloring, and Labeling. The Move and Eraser tools are available in any mode. Other tools are: Point, Segment, Ray, Straight Line, Circle, Polygon Templates (Regular Polygon, Equilateral Triangle, Isosceles Triangle, Right Triangle, Square, Rhombus, Rectangle, Parallelogram, Trapezoid, Isosceles Trapezoid, Right Trapezoid), Midpoint, Perpendicular Bisector, Angle Bisector, Perpendicular, Parallel, Copy Segment, Copy Angle, Circle by 3 Points, Triangle Center Collection (Incenter, Centroid, Circumcenter, Orthocenter), Tangent, Intersection. Hints: Constructing - Drag a circle or other object directly to the desired point until it snaps. - The Segment tool can be used to extend segments. - It is easier to use the Perpendicular tool selecting a line first. Hints: Decorating - Decorations are used to mark a perpendicular, equal angles or segments. - You cannot create a wrong decoration. For example it is impossible to mark segments as equal if their length is actually different. Hints: Coloring - Choose color and style, then tap a point, a circle, or a segment. - You can create segments and points in the Coloring mode. - You can deselect color to change a style only. - The default color is the rightmost in the palette. Hints: Labeling - To hide/restore a label, choose "-" in the letter wheel and then tap a point on the drawing. Hints: Move tool - The whole drawing can be rotated using two fingers when the Move tool is active. - Tap a line or a circle to see their base points that can be dragged. Let's make geometry fun again!

The GeometrySolver is not just an app, its a canvas and a book too. This app not only solves the geometric shapes, it also teaches you the formulas related to each geometric shape as well as it draws the geometric shapes when solved. This app is designed by an engineer to the perfection with every details in mind. It calculates side, height, diagonals, apothem, diameter, radius, perimeter, circumference, area, lateral area, surface area, volume. Some shapes have a dedicated interactive tab to play around and draw those shapes of different dimensions. Each geometric shape has its corresponding formulas written beautifully in mathematical way. This is a perfect app for your kids to learn geometry interactively. Draw, solve, share the geometric shapes. Drawn/solved shapes are displayed with their properties (numeric values). The Solve tab of angle is dynamic and interactive. You can touch/drag on the surface to draw an angle or use the slider to draw an angle. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. There are so many common geometric shapes to learn from like square, circle, cylinder, cone, cuboid, pyramid, sphere and more There is also a Study page to help you with learning formulae related to many common geometric shapes. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
