And we use that information and the Pythagorean Theorem to solve for x. So this is x over two and this is x over two. Two congruent right triangles and so it also splits this base into two. Once we recognize the triangle as isosceles, we divide it into congruent right triangles. So the key of realization here is isosceles triangle, the altitudes splits it into We can find the area of an isosceles triangle using the Pythagorean theorem.

So this length right over here, that's going to be five and indeed, five squared plus 12 squared, that's 25 plus 144 is 169, 13 squared. This distance right here, the whole thing, the whole thing is So x is equal to the principle root of 100 which is equal to positive 10. But since we're dealing with distances, we know that we want the This purely mathematically and say, x could be Is equal to 25 times four is equal to 100. We can multiply both sides by four to isolate the x squared. So subtracting 144 from both sides and what do we get? On the left hand side, we have x squared over four is equal to 169 minus 144. That's just x squared over two squared plus 144 144 is equal to 13 squared is 169. This is just the Pythagorean Theorem now.

We can write that x over two squared plus the other side plus 12 squared is going to be equal to We can say that x over two squared that's the base right over here this side right over here. Let's use the Pythagorean Theorem on this right triangle on the right hand side. There may be so many different ways in order to calculate the are the area of an isosceles triangle, here the math formula that we are used as B/4((4aa)-(bb)). And so now we can use that information and the fact and the Pythagorean Theorem to solve for x. Therefore, the angles will also be two equal () and the other different (), this being the angle formed by the two equal sides (a). So this is going to be x over two and this is going to be x over two. The isosceles triangle is a polygon of three sides with two equal sides.The other side unequal is called the base of the triangle.

So they're both going to have 13 they're going to have one side that's 13, one side that is 12 and so this and this side are going to be the same. And since you have twoĪngles that are the same and you have a side between them that is the same this altitude of 12 is on both triangles, we know that both of these So that is going to be the same as that right over there. Because it's an isosceles triangle, this 90 degrees is the Is an isosceles triangle, we're going to have twoĪngles that are the same. Well the key realization to solve this is to realize that thisĪltitude that they dropped, this is going to form a right angle here and a right angle here and notice, both of these triangles, because this whole thing To find the value of x in the isosceles triangle shown below.
