For an isosceles right triangle with side lengths a, the hypotenuse has length sqrt (2)a, and the area is Aa2/2. An isosceles right triangle therefore has angles of 45 degrees, 45 degrees, and 90 degrees. An Isosceles Right Triangle is a right triangle that consists of two equal length. Subject classifications A right triangle with the two legs (and their corresponding angles) equal. The legs (or their lengths) are often labeled a and b.Įither of the legs can be considered a base and the other leg would be considered the height (or altitude), because the right angle automatically makes them perpendicular. Isosceles Right Triangle Isosceles Right Triangle Definition. An equilateral triangle is a triangle with three congruent sides and three congruent angles. An isosceles triangle is a triangle with two congruent sides and one unique side and angle. When using the Pythagorean Theorem, the hypotenuse or its length is often labeled with a lower case c. The six types of triangles are: isosceles, equilateral, scalene, obtuse, acute, and right. Triangles have some very handy properties. The sides adjacent to the right angle are the legs. A particular type of triangle is the isosceles right triangle, which has two equal sides and one right angle. The word isosceles is pronounced eye-sos-ell-ease with the emphasis on the sos. The side opposite of the right angle is called the hypotenuse. A triangle which has two of its sides equal in length. Right triangles have special properties which make it easier to conceptualize and calculate their parameters in many cases. Right triangles are ]s in which one of the interior angles is 90 o. Isosceles right triangle: The following is an example of a right triangle with two legs (and their corresponding angles) of equal measure.

Also, the two angles opposite the two equal sides are equal. 3 Sine, Cosine, and Tangent for Right Triangles Practice Questions FAQs What is Isosceles Triangle An Isosceles triangle is a triangle that has two equal sides.
