<span>3. Two isosceles right triangles
Every square has 4 right angles, so each triangle will have one right triangle, which makes the triangles, right triangles. 
They are isosceles because all sides of the square are the same, though the diagonal is not.
Hope this helps :)

Answer:
increase
Step-by-step explanation:
First, we need to find the mean of the given data set without any change.
10 + 61 + 10 + 44 + 21 + 79 + 27 + 12 = 264
264 ÷ 8 = <u>33</u>
Now that we have the mean, we can find the mean of the data set with the change of 52.
10 + 61 + 10 + 44 + 21 + 79 + 27 + 52 = 304
304 ÷ 8 = <u>38</u>
<u />
From this, we can see that the mean has increased with the change of 12 to 52. Thus, that's the correct option.
hope this helps!
