#Practical use of kite shape plus

The square root of 1 plus 9 is the square root of 10, and that’s the same thing that we got for the distance from A to B, so that means the distances from A to B and B to C are equal, and since the distances are equal that means those segments are congruent, so I’m going to mark those congruent. Negative 1 squared, is 1, plus, 3 squared is 9. Again, we’re going to simplify underneath the radical first, starting with our parentheses.ġ minus 2, or plus a negative 2, is negative 1 squared, plus, 3 minus 0 is 3 squared. I’m using the distance formula again, so the square root of x_2, (using B and C) so x_2 is 1, minus x_1 is 2, squared, plus, y_2 is 3, minus y_1 is 0, squared. Now I’m going to find the distance between points B and C.

I’m not actually going to solve for the square root of 10 and find the actual square root of the number, the square root of 10 is good enough for our purposes. The square root of 10 is an irrational number meaning that it goes on forever, its decimal does not end, but it’s not really important what the distance is, what’s important is if my distances are equal. Now we need to simplify underneath the radical, starting with the parentheses, so that equals the square root of, (can add the inverse) 1 plus 2 is 3, squared, plus, 3 minus 2 is 1, squared, that equals the square root of 3 squared is 9, plus, 1 squared is 1, so that equals the square root of 10. First, I want to find the distance from A to B, so that’s the square root of x_2 is 1, minus x_1 is negative 2, squared, plus, y_2 is 3, minus y_1 is 2, squared. In one point, like point A, you couldn’t call one coordinate x_1 and then the other one y_2, so as long as you don’t mix it up like that, you can label any of the points x_1, y_1, x_2, y_2, it doesn’t matter. We’re going to use the distance formula, which is distance equals the square root of x_2 minus x_1, squared, plus, y_2 minus y_1, squared, (and I’ve already put the labels on all of my points) and it doesn’t matter which point you call x_1, y_1, or x_2, y_2, as long as you’re consistent. In order to tell if they’re congruent, I’m going to find the distance between the points, and if the distances between the points are the same, then that means that those segments are congruent.

That means that I need to show that both pairs of my adjacent sides are congruent, or that I have two pairs of adjacent sides that are congruent. I’m going to use the first method to determine if this quadrilateral, ABCD, is a kite. You can use either of these things to determine if a quadrilateral is a kite. A kite also has perpendicular diagonals, where one bisects the other. A kite is a quadrilateral with two pairs of adjacent sides, congruent. Determine if quadrilateral ABCD is a kite.
