# What is another name for 45 45 90?

The 45°-45°-90° right triangle is sometimes referred to as an isosceles right triangle because it has two equal side lengths and two equal angles.

## What is the shortest side of a 30-60-90 triangle?

And so on. The side opposite the 30° angle is always the smallest, because 30 degrees is the smallest angle. The side opposite the 60° angle will be the middle length, because 60 degrees is the mid-sized degree angle in this triangle.

## What are the sides of 30-60-90 triangle?

The sides of a 30-60-90 triangle are identified by their relation to the angles. The side opposite the 30-degree angle is called the shorter leg. The side opposite the 60-degree angle is called the longer leg. The side opposite the right angle of 90 degrees is called the hypotenuse.

## What is a true statement about a 45 45 90 triangle?

what is a 45-45-90 triangle? an isosceles right triangle with interior angle measures of 45 degrees, 45 degrees, and 90 degrees.

## What is a 45 degree triangle?

A 45 – 45 – 90 degree triangle (or isosceles right triangle) is a triangle with angles of 45°, 45°, and 90° and sides in the ratio of. Note that it’s the shape of half a square, cut along the square’s diagonal, and that it’s also an isosceles triangle (both legs have the same length).

## What is a 45 degree triangle called?

For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an “angle-based” right triangle. A “side-based” right triangle is one in which the lengths of the sides form ratios of whole numbers, such as 3 : 4 : 5, or of other special numbers such as the golden ratio.

## What is the length of the hypotenuse each leg of a 45 45 90 triangle measures 12 cm?

Summary: Each leg of a 45°-45°-90° triangle measures 12 cm. The length of the hypotenuse is 16.97cm.

## What is in the scalene triangle?

A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures. Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent.

## What is the relationship of the hypotenuse to the shorter leg of a 30 60 90 triangle?

The hypotenuse is equal to twice the length of the shorter leg, which is the side across from the 30 degree angle. The longer leg, which is across from the 60 degree angle, is equal to multiplying the shorter leg by the square root of 3.

## What have you observed in a 45 45 90 right triangle Aside from the two legs are congruent The sides are also equal to?

A 45 45 90 triangle is a special type of isosceles right triangle where the two legs are congruent to one another and the non-right angles are both equal to 45 degrees. Many times, we can use the Pythagorean theorem to find the missing legs or hypotenuse of 45 45 90 triangles.

## What angles are 90 degrees?

Angles that are 90 degrees (θ = 90°) are right angles. Angles that are 180 degrees (θ = 180°) are known as straight angles.

## What is the length of the hypotenuse?

In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.

## What is the length of the hypotenuse of the triangle below 5 2 5 2?

Correct answer: And since it is a 45-45-90 triangle the two short sides are equal. Therefore 52 + 52 = h2 . Multiplied out 25 + 25 = h2. Therefore h2 = 50, so h = √50 = √2 * √25 or 5√2.

## Is the hypotenuse of a 45 45 90 triangle is twice as long as one of its legs?

That is, the legs of this 45-45-90 triangle are equal. Applying the Pythagorean theorem we find that the length of the hypotenuse is equal to the square root of 2. In other words, the hypotenuse is root 2 times the length of either leg.

## What is the difference between a 45 degree angle and a 90-degree angle?

A 45-degree angle is exactly half of a 90-degree angle formed between two rays. It is an acute angle and two angles measuring 45 degrees form a right angle or a 90-degree angle.

## What are the correct proportions for sides a B and C in the following 45 45 90 right triangle?

45 45 90 triangle ratio In a 45 45 90 triangle, the ratios are equal to: 1 : 1 : 2 for angles (45° : 45° : 90°) 1 : 1 : √2 for sides (a : a : a√2)

## What is the exact value of cos 45?

The exact value of cos 45 degrees is 1/√2 (in surd form), which is also equal to sin 45 degrees. It is an irrational number, equal to 0.7071067812… in decimal form. The approximate value of cos 45 is equal to 0.7071.

## What theorem will you use to find the length of the hypotenuse of a 45 45 90?

Correct answer: 45/45/90 triangles are always isosceles. This means that two of the legs of the triangle are congruent. In the figure, it’s indicates which two sides are congruent. From here, we can find the length of the hypotenuse through the Pythagorean Theorem.

## Which triangle is a 30-60-90 triangle quizlet?

What is right triangle is a triangle with angle measures of 30°, 60°, and 90°. In a 30°-60°-90° right triangle, the measure of the hypotenuse is twice the measure of the short leg, and the measure of the longer leg is the measure of the short leg times √3 . You just studied 2 terms!

## What is the length of the hypotenuse of the triangle quizlet?

The length of the hypotenuse equals the length of a leg multiplied by square root of 2 (approximately 1.4). If x is the length of the side opposite the 30° angle, the side opposite the 60° angle equals x square root of 3 (approximately 2.73) and the side opposite the 90° angle equals 2x. Side opposite of the angle.
