What is the relationship between the sides of a 30-60-90 triangle?

In a 30-60-90 triangle, the lengths of the sides are in the ratio 1 : $$\frac{{\text{√3}}}{{2}} : 2$$ .

What is the relationship between the sides of a 45-45-90 triangle?

In a 45-45-90 triangle, the lengths of the legs are equal, and the hypotenuse is $$\text{leg} \times \text{√2}$$ .

How do you estimate the square root of a number?

To estimate the square root, find two perfect squares between which the number lies and then approximate.

What is the value of $$\frac{{1}}{{2}}$$ of $$\text{hypotenuse}$$ in a right triangle?

The value of $$\frac{{1}}{{2}}$$ of the hypotenuse is half the length of the hypotenuse.

If a triangle has sides of length 7.8 and 3.3, what is the length of the hypotenuse?

Using the Pythagorean Theorem: $$c^2 = 7.8^2 + 3.3^2$$ , calculate to find the hypotenuse.

What is the approximate value of $$\text{sqrt}(20)$$ ?

The approximate value of $$\text{sqrt}(20)$$ is about 4.5.

What is the significance of the Pythagorean Theorem in real life?

The Pythagorean Theorem is used in various fields such as architecture, construction, and navigation to determine distances and angles.

How can the Pythagorean Theorem be applied to find distances in coordinate geometry?

In coordinate geometry, the distance between two points (x1, y1) and (x2, y2) can be found using the formula: $$d = \text{sqrt}((x2 - x1)^2 + (y2 - y1)^2)$$ .
