App Description

Enter a whole new world of learning geometry and become a 21st century learner with this AC Geometry app. Start learning today with standards-based content presented with highly interactive explorations, visual explanations, animations, and hands-on exercises. Get ready to experience exciting, instructionally focused math activities with hands-on interactivity.

Define a rhombus, explore its properties and their proofs, and use these properties to solve problems. Observe that the opposite angles of a rhombus are congruent, consecutive interior angles are supplementary, and diagonals are angle bisectors and perpendicular bisectors of each other. Form a rhombus and determine any unknown lengths or angles when related information is provided.

• Learn about the definition of a rhombus through an engaging real-life example.
• Observe the properties of a rhombus by creating your own rhombuses.
• Use the properties of a rhombus to solve problems.
• Work with different problems for more practice and learn from your mistakes.

App features:
• Take charge! Explore geometry in an engaging and interactive environment.
• Experience hands-on interactions, not just words and pictures on a page.
• Practice what you learn and receive helpful feedback.
• Investigate challenging topics with step-by-step support.
• Demonstrate what you learn by taking quizzes.
• Want more? Check out the AC library in the App Store.
