The Bermuda Triangle. The Bermuda Triangle has been a mystery to mankind for many centuries. Myths and legends have been formed about the small area of ocean, which seems to swallow planes, ships, and people. The area of ocean is a section of the West Atlantic off of the southeastern coast of the United States.
A triangle that has one right angle is called a right triangle. A triangle that has one obtuse angle is called an obtuse triangle. When a triangle has three congruent sides, we call the triangle an equilateral triangle. We mark the congruent sides by a slash mark. The angles in an equilateral triangle are always 60Â°. When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle. When two triangles are congruent it means that they have the same size and shape. This means that they have the same angles.
