## What type of triangle is a 45 45 90 right triangle?

isosceles triangles

Recall that the 45 45 90 special right angle triangle is an isosceles triangles with two equal sides and the one larger side (i.e. hypotenuse definition).

**What type of triangle is a triangle with two 45-degree angles?**

A right isosceles triangle has a 90-degree angle and two 45-degree angles. This is the only right triangle that is an isosceles triangle.

**What are the rules for a 45 45 90 triangle?**

The main rule of 45-45-90 triangles is that it has one right angle and while the other two angles each measure 45° . The lengths of the sides adjacent to the right triangle, the shorter sides have an equal length.

### How do you know if it is a 45 45 90 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 are the side lengths of a 90 45 45 triangle?**

A 45°-45°-90° triangle is a special right triangle that has two 45-degree angles and one 90-degree angle. The side lengths of this triangle are in the ratio of; Side 1: Side 2: Hypotenuse = n: n: n√2 = 1:1: √2. The 45°-45°-90° right triangle is half of a square.

**How do you find the area of a 45 45 90 triangle?**

To find the area of a triangle, multiply the base by the height, then divide by 2. Since the short legs of an isosceles triangle are the same length, we need to know only one to know the other. Since, a short side serves as the base of the triangle, the other short side tells us the height.

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

Question: Which is a true statement about a 45-45-90 triangle? Each leg is times as long as the hypotenuse. The hypotenuse is times as long as either leg.

**What are the legs of a 45 45 90 triangle?**

The two legs of a 45-45-90 triangle are always the same length. The legs are the two sides that form the right angle: the 5 and the b. This means that b is also 5. To find the hypotenuse, we can use the shortcut and simply multiply the leg by the square root of 2.
