Online Triangle Solver

Online Triangle Solver

TrianCal - Open in Google Chrome. (Triangles online calculator developed by Jesus S.) I propose this free online calculator triangles without advertising to help students with geometry, does not perform the duties, because their calculations formulas are not displayed. It is designed in a didactic way to check and view the realized duties. TrianCal is online calculator triangles that works with any combination of values including sides, heights, angles, the area, perimeter or type of any triangle, calculating it with the minimum possible value (typically three). Other functions: - Draw the triangle (s) with GeoGebra. - Set the range of values in each element. - Chande name of vertex - The type of angle. - The type of triangle by its angles and sides. - Selection of language (English or Spanish). - Select the angle type [degrees (°), radians, degrees, minutes and seconds (° ' ") or degrees and minutes (° ')]. - Number of decimal places shown in the results (0-15). - You can use the arrow keys and the Tab key to navigate through the settings. - Drop-down menu to select the values comfortably. - Create a link (URL) to the current triangle. - An icon mail to communicate with the author. NOTE: You must use the Google Chrome browser to display correctly TrianCal. Examples of possible combinations: - The area, perimeter and other data (side, height or angle), if the outside equilateral triangle would not need the third data. - 2 angles and other data (if the value of the other data is not put aside the value of "a" at the time of drawing the triangle is 10).

Maths Mastery - Geometry and Measures Revision Maze (Full answers included)

Maths Mastery - Geometry and Measures Revision Maze (Full answers included)

A fantastic resource revising geometry and measures, in particular, applying Pythagoras' Theorem, area and perimeter of trapeziums as well as fractions, ratio etc. Students must work out the answers to move across the maze, the questions increase in difficulty as you cross the maze to challenge the more able and support the less able in your class.

Missing lengths & compound shapes - introductory questions

Missing lengths & compound shapes - introductory questions

This is a topic that many pupils find extremely difficult to grasp. I tried to simplify it as much as possible by reducing the complexity with the following questions, focusing only on finding missing lengths given several horizontal or vertical lines.
