Question

Third coordinate of isosceles triangle when length and angle is given

Answer 1

Answer:

One important property of an isosceles triangle is that the angles opposite the equal sides are equal. The converse is also true: if two or more angles in a triangle are equal, then the sides opposite these equal angles are equal (and so the triangle is isosceles)

Step-by-step explanation:

To find an unknown side of a triangle, you must know the length of other two sides and/or the altitude. To find the unknown base of an isosceles triangle, using the following formula: 2 * sqrt(L^2 - A^2), where L is the length of the other two legs and A is the altitude of the triangle.
