Answer:
The area of triangle is 120 cm².
Step-by-step explanation:
First, you have to calculate the height of the triangle using Pythogorem Theorem :
![{a}^{2} + {b}^{2} = {c}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%2B%20%20%7Bb%7D%5E%7B2%7D%20%20%3D%20%20%7Bc%7D%5E%7B2%7D%20)
Let a = base = 10 cm,
Let b = height = h cm,
Let c = hypotenuse = 26 cm,
![{10}^{2} + {h}^{2} = {26}^{2}](https://tex.z-dn.net/?f=%20%7B10%7D%5E%7B2%7D%20%20%2B%20%20%7Bh%7D%5E%7B2%7D%20%20%3D%20%20%7B26%7D%5E%7B2%7D%20)
![{h}^{2} = {24}^{2} - {10}^{2}](https://tex.z-dn.net/?f=%20%7Bh%7D%5E%7B2%7D%20%20%3D%20%20%7B24%7D%5E%7B2%7D%20%20-%20%20%7B10%7D%5E%7B2%7D%20)
![{h}^{2} = 576](https://tex.z-dn.net/?f=%20%7Bh%7D%5E%7B2%7D%20%20%3D%20576)
![h = \sqrt{576}](https://tex.z-dn.net/?f=h%20%3D%20%20%5Csqrt%7B576%7D%20)
![h = 24 \: cm](https://tex.z-dn.net/?f=h%20%3D%2024%20%5C%3A%20cm)
We have found out that the height is 24 cm. Next, we have to use the area of triangle formula :
![area = \frac{1}{2} \times base \times height](https://tex.z-dn.net/?f=area%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20base%20%5Ctimes%20height)
Let base = 10cm,
Let height = 24cm,
![area = \frac{1}{2} \times 10 \times 24](https://tex.z-dn.net/?f=area%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%2010%20%5Ctimes%2024)
![area = \frac{1}{2} \times 240](https://tex.z-dn.net/?f=area%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20240)
![area = 120 \: {cm}^{2}](https://tex.z-dn.net/?f=area%20%3D%20120%20%5C%3A%20%20%7Bcm%7D%5E%7B2%7D%20)

Answer:
<h2>Ray.</h2>
Step-by-step explanation:
The statement is the definition of a ray.
In geometry, a ray is half of a line, beacuse it begins at specific point and extends to the infinite, while a line extends from an infinite point to an another infinite point. So, basically, the difference is that a ray starts at a determined point, while a line doesn't.
Therefore, the answer is Ray.
