![]() ![]() 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. :)□ĪDD: #^2+#^2= x^2 ( the # represents ANY number, and the x represents the variable) So you will inverse the addition into subtraction. If u took that before, when we have a variable with an operation (NOT THE RESULT) u need to INVERSE the operation to find that answer. They will give you the value of one of the legs, and the hypotenuse, but one leg would be x. Listen, sometimes they want you to find the missing LEG, not the hypotenuse. So keep in your AWESOME mind that when we need to find the hypotenuse, we have the value of the legs, so we put them instead of A and B// And in that case, you ADD.□ When the hypotenuse is missing, we SHOULD add because I mentioned b4 that c^2// aka the longest side and called the HYPOTENUSE. *How do we know when do we need to add or subtract in the PT? HOW do you identify the hypotenuse? EZ! Just look at the longest side of a right triangle! □ ~RECAP done! The Pythagorean theorem is a theory that states: a^2+B^2=c^2 Ok, keep your eyes open!□We want to UNDERSTAND! ![]()
