Parts of a right angle triangle
WebThe side opposite the right angle is called the hypotenuse . It is the largest side of a right-angled triangle. If you stand at A in the triangle ABC, the side BC is opposite to you and the side AB is next to you. We therefore say that BC is the opposite side to angle A and AB is the adjacent side to angle A.

Web18 Nov 2024 · A right triangle is a special case of a scalene triangle, in which one leg is the height when the second leg is the base, so the equation gets simplified to: area = a × b / 2. For example, if we know only the right triangle area and the length of the leg a, we can … An isosceles right triangle is a special right triangle, sometimes called a 45-45-90 … In a right triangle, the sides that form the right angle will have slopes whose … In some situations, you don't need to know the exact result of the square root. If this … Web2 Feb 2024 · What is the area of a right triangle with hypotenuse 5 cm and angle 45°? The area is 6.25. We get this answer by applying the formula area = c² × sin (α) × cos (α) / 2 with c = 5 and α = 45°. The math theorem used to derive this formula is called the law of sines. How do I know if it is a right triangle?
WebA right triangle (or right-angled triangle) has one of its interior angles measuring 90° (a right angle). The side opposite to the right angle is the hypotenuse, the longest side of the … WebTo find the area of a right triangle we only need to know the length of the two legs. 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.
WebThe sides of a right triangle are commonly referred to with the variables a, b, and c, where c is the hypotenuse and a and b are the lengths of the shorter sides. Their angles are also …
