Right Triangles

Right triangle, a triangle that has a degrees of 90. The angle of this triangle has a C to the power of 2 set to 90 degrees. The angle is always facing up and to the left or right. Looks similar to an angle on a Christian cross stick. The triangle will always have 3 sides. The triangle can be facing left or right. It can even be facing diagonal if it has a 90 degree angle. The right triangle is always at 90 degrees. All triangles have a 3-sided polygon because it is a 2 dimensional figure and is closed sided.

The reason it is called the “right triangle” is because the angle is opposite of the hypotenuse. The hypotenuse is the side that connects point A and point B. The degree of the hypotenuse is 180 degrees. The line for the hypotenuse is always straight. The hypotenuse is always on the right triangle.

The right triangle follows the A^2+B^2=C^2 formula. It is a formula that is used to determine the length of the hypotenuse. Hypotenuse is the longest side on the triangle. This ABC formula is often used in Geometry and in Algebra classes. It is designed to show students how to figure out the length of a 3 sided polygon. There are different formulas used in math to determine the area of a triangle and sometimes used to determine the angle of a triangle.

The concept of the right triangle started in 3000 BC in Egypt. Egyptians would use the right triangle to measure the length of things. They would get ropes and tie them in a right triangle. Then, they would put knots on the ropes to determine how long and far they needed to go. They used this to build temples and inside structures. They would count the rope knots to get a number of measurement.
