**finding angles in isosceles triangles? Yahoo Answers**

Therefore each of the two triangles is isosceles and has a pair of equal angles. But all of these angles together must add up to 180°, since they are the angles of the original big triangle. Therefore x + y + x + y = 180, in other words 2(x + y) = 180.... Therefore each of the two triangles is isosceles and has a pair of equal angles. But all of these angles together must add up to 180°, since they are the angles of the original big triangle. Therefore x + y + x + y = 180, in other words 2(x + y) = 180.

The following two theorems — If sides, then angles and If angles, then sides — are based on a simple idea about isosceles triangles that happens to work in both directions: If sides, then angles: If two sides of a triangle are congruent, then the angles opposite those sides are congruent.... 13/12/2009 · The Law of Cosines is indeed the way to go. In any triangle, with sides of a, b, and c, the size of any side is related to the sizes of the other two and the angle between them.

- 13/12/2009 · The Law of Cosines is indeed the way to go. In any triangle, with sides of a, b, and c, the size of any side is related to the sizes of the other two and the angle between them.
- Therefore each of the two triangles is isosceles and has a pair of equal angles. But all of these angles together must add up to 180°, since they are the angles of the original big triangle. Therefore x + y + x + y = 180, in other words 2(x + y) = 180.
- By working through these exercises, you now are able to recognize and draw an isosceles triangle, mathematically prove congruent isosceles triangles using the Isosceles Triangles Theorem, and mathematically prove the converse of the Isosceles Triangles Theorem. You also should now see the connection between the Isosceles Triangle Theorem to the Side Side Side Postulate and the Angle Angle …
- The following two theorems — If sides, then angles and If angles, then sides — are based on a simple idea about isosceles triangles that happens to work in both directions: If sides, then angles: If two sides of a triangle are congruent, then the angles opposite those sides are congruent.
