Right triangle - Wikipedia
A right triangle (American English) or right-angled triangle (), or more formally an orthogonal triangle, formerly called a rectangled triangle (Ancient Greek: ὀρθόςγωνία, lit. 'upright angle'), is a triangle in which one angle is a right angle (that is, a 90-degree angle) or two sides are perpendicular.The relation between the sides and other angles of the right triangle is the ...
Right Triangles Calculator
A right triangle is a special case of a triangle where 1 angle is equal to 90 degrees. In the case of a right triangle a 2 + b 2 = c 2. This formula is known as the Pythagorean Theorem. In our calculations for a right triangle we only consider 2 known sides to calculate the other 7 unknowns. For example, if we know a and b ...
A right-angled triangle (also called a right triangle) is a triangle with a right angle (90°) in it. The little square in the corner tells us it is a right angled triangle (I also put 90°, but you don't need to!) The right angled triangle is one of the most useful shapes in all of mathematics! ...
Right Triangle Calculator | Pi Day
We don’t need the hypotenuse at all. That’s because the legs determine the base and the height of the triangle in every right triangle. So we use the general triangle area formula (A = base • height/2) and substitute a and b for base and height. So our new formula for right triangle area is A = ab/2. How to find the Perimeter of a Right ...
