## What are the special angles of a right triangles?

45-45-90 triangles

The special properties of both of these special right triangles are a result of the Pythagorean theorem.

**How do you solve a 45 45 90 special right triangle?**

And what you can think of is you can think of this as a square. That’s been cut in half on the diagonal. So if you were to look at this originally. All these sides would be ax.

**What are the angle measures of the triangle 45 45 90?**

A 45-45-90 triangle is a right triangle having interior angles measuring 45°, 45°, and 90°. A 45-45-90 triangle is also an isosceles triangle, which means its two legs are equal in length.

### What are the 2 types of special right triangles?

There are three types of special right triangles, 30-60-90 triangles, 45-45-90 triangles, and Pythagorean triple triangles.

**What is another name for 45 45 90 right triangle?**

isosceles right triangle

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 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.

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

right triangle

A 30-60-90 triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle). Because the angles are always in that ratio, the sides are also always in the same ratio to each other.

**What are the angle measures in a 30 60 90 right triangles?**

What is a 30-60-90 Triangle? A 30-60-90 triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle). Because the angles are always in that ratio, the sides are also always in the same ratio to each other.

**What is a 30 60 90 right triangle theorem?**

One of the two special right triangles is called a 30-60-90 triangle, after its three angles. 30-60-90 Theorem: If a triangle has angle measures 30 ∘ , 60 ∘ and , then the sides are in the ratio x : x 3 : 2 x . The shorter leg is always , the longer leg is always , and the hypotenuse is always .

**Does 7 24 25 make a right triangle?**

Yes, 7, 24, 25 is a Pythagorean Triple and sides of a right triangle. Plug the given numbers into the Pythagorean Theorem.

### Does 9 12 15 form a right triangle?

Which set of sides could make a right triangle? Explanation: By virtue of the Pythagorean Theorem, in a right triangle the sum of the squares of the smaller two sides equals the square of the largest side. Only 9, 12, and 15 fit this rule.

**What is the other name for a 45 45 90 triangle?**

The 45°-45°-90° right triangle is half of a square.

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 are the angle measures in a 30 60 90 right triangles quizlet?**

A right triangle with interior angle measures of 30°, 60°, and 90°. In a 30-60-90 triangle, the hypotenuse is always twice as long as the shorter leg and the longer leg is √3 times as long as the shorter leg. An isosceles right triangle with interior angle measures of 45°, 45°, and 90°.

#### How do you find the measure of a 30 60 90 triangle?

30°-60°-90° Triangles

In a 30°−60°−90° triangle, the length of the hypotenuse is twice the length of the shorter leg, and the length of the longer leg is √3 times the length of the shorter leg.

**What are the angles of a 3 4 5 triangle?**

3-4-5 Triangle Angles

In the 3-4-5 triangle, the right angle is, of course, 90 degrees. The other two angles are always 53.13 degrees (opposite the 4 side) and 36.87 degrees (opposite the 3 side). Maintaining the ratios of this triangle also maintains the measurements of the angles.

**Does 8 15 17 form a right triangle?**

Yes, 8, 15, 17 is a Pythagorean Triple and sides of a right triangle.

### Does 12/16 20 Make a right triangle?

The equation is true! So, a triangle with side lengths 12, 16, and 20 is a right triangle.
