Using only elementary geometry, determine angle x. Provide a step-by-step proof.
You may only use elementary geometry, such as the fact that the angles of a triangle add up to 180 degrees and the basic congruent triangle rules (side-angle-side, etc.). You may not use more advanced trigonomery, such as the law of sines, the law of cosines, etc. There is a review of elementary geometry below.

Use SAGE for studying a huge range of mathematics, including algebra, calculus, elementary to very advanced number theory, cryptography, numerical computation, commutative algebra, group theory, combinatorics, graph theory, and exact linear algebra.

These are some educational java applets written by Paul Falstad to help visualize various concepts in math, physics, and engineering. You should be able to view them with any Java-capable browser.

The Adventures of Jasper Woodbury consists of 12 videodisc-based adventures (plus video based analogs, extensions and teaching tips) that focus on mathematical problem finding and problem solving. Each adventure is designed from the perspective of the standards recommended by the National Council of Teachers of Mathematics (NCTM). In particular, each adventure provides multiple opportunities for problem solving, reasoning, communication and making connections to other areas such as science, social studies, literature and history (NCTM, 1989; 1991)

Absurd Math is an interactive mathematical problem solving game series. The player proceeds on missions in a strange world where the ultimate power consists of mathematical skill and knowledge. Many of the pages have hidden clues and areas. Anytime a player needs help, they may email our staff for assistance. We try to respond within two days. Teachers and parents, email us for answer keys.

"An American Imperative" addresses the critical shortage of high quality mathematics and science teachers, the lack of which threatens the strength, innovation, and productivity of America's economy. The report proposes a comprehensive action plan to elevate the status of the teaching profession and focuses on transforming three key components that contribute to a robust, world-class teaching workforce: recruitment, retention, and renewal.

This page offers a better way to create a strong, yet easy to
remember passphrase for use with encryption and security programs.
Weak passwords and passphrases are one of the most common flaws in
computer security. Take a few minutes and learn how to do it right.
The information presented here can be used by anyone. No background
in cryptography or mathematics is required.

Research shows that the difference between what is taught and what is learned is often greater than most instructors realize. Lillian McDermott from the University of Washington discusses current and future trends in math and science education.
