Mathematicians struggled to find the fewest number of pieces needed to cut an equilateral triangle and rearrange it into a ...

Now, more than 122 years after it was first proposed, Kamata and two other mathematicians have finally proved that a solution ...

With all that​ emphasis on the significance of the square in our lives, how did we get to that semi-put down of the middle of the last century “Be there or be square”?

A rectangle has two pairs of equal sides. It has four right angles (90°). The opposite sides are parallel. The diagonals bisect each other. A parallelogram has two pairs of equal sides.

A right angle is exactly 90°. It is shown by a small square. Angles that add together to make a right angle are called complementary angles. If you know one complementary angle you can subtract ...
