A right triangle is a type of triangle that has one angle measuring 90 degrees (a right angle). This particular angle is formed by the intersection of the two sides of the triangle that are perpendicular to each other. The other two angles in a right triangle are acute angles, meaning they are less than 90 degrees.
To determine whether a given triangle is a right triangle, you can follow these steps:
1. Obtain the measures of all three angles of the triangle. The sum of all angles in any triangle is always 180 degrees.
2. Check whether any of the angles measures exactly 90 degrees. If one angle measures 90 degrees, then the triangle is a right triangle.
3. Alternatively, you can also examine the lengths of the triangle's sides. If the square of the length of the longest side (the hypotenuse) is equal to the sum of the squares of the other two sides, then the triangle is a right triangle. This is known as the Pythagorean theorem.
Remember that a right triangle is a special case within the broader category of triangles, and its defining characteristic is the presence of a 90-degree angle.
