What are the legs of a triangle?

A leg of a triangle is one of its sides. For a right triangle, the term "leg" generally refers to a side other than the one opposite the right angle (which is termed the hypotenuse). Legs are also known as catheti.

What are the legs called in a triangle?

The legs (or catheti; singular: cathetus) are the sides in a right triangle that form its right angle (90°). The side opposite the right angle is called the hypotenuse. The legs (or catheti) are the two shorter sides of the triangle.

How many legs does a triangle have?

A right triangle consists of two legs and a hypotenuse. The two legs meet at a 90° angle and the hypotenuse is the longest side of the right triangle and is the side opposite the right angle.

What are the legs of a triangle a B?

a and b are the "legs" of the triangle, which are the two sides that make up the 90 degree angle. c is the "hypotenuse" of the triangle, and is the side of the triangle that is opposite the right angle (another way to say a 90º angle is "right angle"). The hypotenuse is also the longest side of the right triangle.

What is the A and B of a triangle?

Study the right-angled triangle shown. In any right-angled triangle, ABC, the side opposite the right-angle is called the hypotenuse. Here we use the convention that the side opposite angle A is labelled a. The side opposite B is labelled b and the side opposite C is labelled c.

How to determine the hypotenuse, opposite, and adjacent legs of a triangle

What are sides A and B called?

What is the length of the hypotenuse? Sides a and b are called legs. Side c on a right triangle is ALWAYS the longest.

What are legs?

The legs are the two lower limbs of the body. They provide support and a range of movements. Each leg contains five regions. They're known as the: upper leg.

What is leg and hypotenuse?

For a right triangle, the side that is opposite of the right angle is called the hypotenuse. This side will always be the longest side of the right triangle. The other two (shorter) sides are called legs.

Do triangles have 4 sides?

The triangle has three (3) sides. The triangle is a polygon that contains three sides and three inner angles and three vertices.

What are the three sides of a triangle called?

In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles.

What are the parts of a triangle?

Why are triangle sides called legs?

The relation between the sides and other angles of the right triangle is the basis for trigonometry. The side opposite to the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (or catheti, singular: cathetus).

What is the bottom of a triangle called?

Perimeter. Base. Side. This is the side at the bottom of the triangle. The base of a triangle is the side on which it “rests.”

What are each of the sides of a triangle called?

The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs.

What is the length of the legs?

A strict anatomical definition of leg length (LL) is the length of the femur + tibia. Due to the bipedal nature of the human species, “leg length” often is measured as: (femur + tibia + the height of the foot, from the tibia-talus articulation to the ground).

What is the length of each leg of the triangle?

In this type of right triangle, the hypotenuse is always the product of the leg and the square root of 2. So to find the length of each leg, just divide the hypotenuse, 12 , by the square root of 2.

What is the hypotenuse of 3 and 4?

We know that in a 3-4-5 right triangle, when the legs are 3 feet and 4 feet, the hypotenuse will be 5 feet.

What is a leg in geometry?

A leg of a triangle is one of its sides. For a right triangle, the term "leg" generally refers to a side other than the one opposite the right angle (which is termed the hypotenuse). Legs are also known as catheti.

What are leg parts called?

The major bones of the leg are the femur (thigh bone), tibia (shin bone), and adjacent fibula, and these are all long bones. The patella (kneecap) is the sesamoid bone in front of the knee.

How do legs work?

The flexor contracts to bend a limb at a joint. Then, the extensor contracts to extend or straighten the limb at the same joint. For example, to walk, you have to alternately bend and straighten the leg, so the quadriceps (front) and the hamstrings (back) work together to move your leg.

What side is AB and C?

The longest side of a right triangle is called the hypotenuse and it is the side opposite the right angle. AB (also called c) is the hypotenuse.

How do you know what's AB and C in a triangle?

What is side AB?

The 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.
