I think the first photo, to find the answer, you have to add two sides together. If they are greater than the third, it’s a triangle. If not, then it’s not a triangle.

For A on the slide with 4 cards, the two angles labeled x are equal to each other. A triangle has 180 degrees. Subtract the given angle from 180 and divide by two.

I think those clues can Apple to most of the other pictures. That’s the most I can remember from my geometry class.

What is the measure of an interior angle of a regular three-sided polygon?

noname [10]

The formula to find the measure of an interior angle is $(n - 2) * 180/n$ , where $n$ represents the number of sides in the polygon. In this problem, $n$ would represent $3$ .

Let's plug in the value for $n$
$(3 - 2) * 180/3$
Let's simplify that.
$=60$

Now we know that the <span>measure of an interior angle of a regular three-sided polygon is 60</span>°. Your answer would be B!

Let me know if you have any questions regarding this problem!
Thanks!
