## What is the hypotenuse of a triangle?

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. The Pythagorean Theorem tells us that the relationship in every right triangle is: a2+b2=c2.

## What is the HL Theorem?

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

## How do you find the length of a triangle given two sides?

Given two sides of a triangle determine the missing length –

## How do I find the missing length of a triangle?

Finding the missing length of a triangle using pythagorean theorem

## How do you find the side of a triangle given two sides?

How do you find the side of a right triangle given two angles and hypotenuse? Answer: If you know two angles, then you can work out the third since all the angles sum to 180 degrees. If the sides are a, b and the hypotenuse is c (opposite angle A), and the angles are A, B and C, then Sin A = a/c, so a = cSin A.

## What is a unique triangle?

correspondence; three side lengths of a triangle determine a unique triangle. ▪ Students understand that two triangles are identical if two corresponding sides and the included angle are. equal under some correspondence; two sides and an included angle of a triangle determine a unique triangle.

## What is the rule for triangle side lengths?

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. Note: This rule must be satisfied for all 3 conditions of the sides.

## How do work out 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.
