What is the length of BC in the right triangle below?

BC = 39 units. Step-by-step explanation: Use the Pythagorean theorem to solve for BC.

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.
