# What Is Right Angle Hypotenuse Side?

RHS (Right AngleHypotenuseSide) Congruence Theorem. Theorem : Two right triangles are congruent if the hypotenuse and one side of one triangle are respectively equal to the hypotenuse and the corresponding side of the other triangle.

What is right hypotenuse side?

Definition: The longest side of a right triangle. The side opposite the right angle. In a right triangle (one where one interior angle is 90°), the longest side is called the hypotenuse. It is always the side opposite the 90° angle. See Right Triangle definition.

how do you find the sides of a right triangle? Key Points

### what is the formula for a right angle?

The Pythagorean theorem is the formula that relates all three sides of a right triangle to each other. It allows you to find one side given the other two. The side c is always the hypotenuse or the side opposite the right angle. The hypotenuse is always the longest side of a right triangle.

What is RHS congruence rule?

RHS Congruence Rule Theorem: In two right-angled triangles, if the length of the hypotenuse and one side of one triangle is equal to the length of the hypotenuse and one side of the other triangle, then the two triangles are congruent.

### What is another word for hypotenuse?

Synonyms for hypotenuse. ha?ˈp?t nˌus, -ˌyus.

### What is the leg of a right triangle?

Legs of a Right Triangle. The legs of a right triangle are the two sides that intersect to determine the right angle. The remaining side is called the hypotenuse.

### What is a leg of a triangle?

Leg. 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 is the adjacent side?

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.

### How fo you find the area of a triangle?

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

### How do you find the missing side of a triangle?

In this right triangle, you are given the measurements for the hypotenuse, c, and one leg, b. The hypotenuse is always opposite the right angle and it is always the longest side of the triangle. To find the length of leg a, substitute the known values into the Pythagorean Theorem.

### What is hypotenuse leg?

The hypotenuse leg theorem states that any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.

### What do you mean by hypotenuse?

hypotenuse. The hypotenuse is the side of a right triangle that’s opposite the 90-degree angle. It’s a term specific to math, specifically geometry.

### What are the formulas for triangles?

Pythagoras’ theorem states that in a right triangle (or right-angled triangle) the sum of the squares of the two smaller sides of the triangle is equal to the square of the hypotenuse. Geometry Formulas Triangles – Pythagoras’ Theorem [ c = sqrt {a^2 + b^2} ] [ b = sqrt {c^2 – a^2} ] [ a = sqrt {c^2 – b^2} ]

### What is the 3 4 5 Triangle rule?

The 3:4:5 triangle is the best way I know to determine with absolutely certainty that an angle is 90 degrees. This rule says that if one side of a triangle measures 3 and the adjacent side measures 4, then the diagonal between those two points must measure 5 in order for it to be a right triangle.
