Question

Determine which angles are right triangles. Select all that apply

Answer 1

`A,B`

Step-by-step explanation:

Here, we want to get the right triangles

Mathematically, for us to have a right triangle, the square of the hypotenuse (which is the longest side) equals the sum of the squares of the two other sides. This is Pythagoras' theorem

We shall be testing this principle out on the given options

We proceed as follows:

`\begin{gathered} a)\text{ 24}^2\text{ + 143}^2\text{ = 145}^2 \\ b)\text{ 28}^2\text{ + 195}^2\text{ = 197}^2 \\ c)\text{ 135}^2\text{ + 140}^2\text{ }\\e\text{ 175}^2 \\ d)\text{ 56}^2+\text{ 16}^2\\e\text{ 65}^2 \end{gathered}`

What this means is that only options A and B is correct
