## What is the length of BC in the right triangle below 21 72?

The answer is 75, hope i helped!

## What is the length of BC in the right triangle below 22 120?

Answer: B. BC = 122 units. AC = 120 units.

## Is Wxy a right triangle?

a^2+b^2=c^2 where a and b are the two shorter legs and c is the hypotenuse. If a^2+b^2 is equal to c^2, then it is a right triangle. Because a^2+b^2 equals c^2, you can conclude that triangle WXY is a right triangle.

## Is def a right triangle?

Triangle def is a right triangle, and angles d and f are equal but are not right angles.

## Are two sides of a right triangle equal?

You’ve already met the right triangle in an earlier lesson. A right triangle has one angle equal to 90 degrees. A right triangle can also be an isosceles triangle–which means that it has two sides that are equal. A right isosceles triangle has a 90-degree angle and two 45-degree angles.

## Why is a right triangle a right triangle?

A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The side opposite the right angle is called the hypotenuse (side c in the figure).

## What is not true about a right triangle?

Properties. A right triangle can never be equilateral, since the hypotenuse (the side opposite the right angle) is always longer than either of the other two sides.

## Which is the shortest side of a right triangle?

In any triangle, the longest side is opposite the largest angle, and the shortest side is opposite the smallest angle. Thus, in a right triangle, the hypotenuse is always the longest side.

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

Right Triangles and the Pythagorean Theorem

1. The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
2. The side opposite the right angle is called the hypotenuse (side c in the figure).

## What is the formula for the length of a line?

1. Distance between two points P(x1,y1) and Q(x2,y2) is given by: d(P, Q) = √ (x2 − x1)2 + (y2 − y1)2 {Distance formula} 2.

## What is the length of square?

Since each side of a square is the same, it can simply be the length of one side squared. If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches.
