WebMar 31, 2024 · The side-angle-side theorem is one of three theorems for showing that two triangles are congruent; the other two are the angle-side-angle (ASA) theorem and the side-side-side (SSS) theorem. In Euclid ’s Elements, the side-angle-side theorem is Proposition 4 in Book I. Euclid proved the theorem as follows: there are two triangles ABC and DEF. WebThe theorem can also be thought of as a special case of the intersecting chords theorem for a circle, since the converse of Thales' theorem ensures that the hypotenuse of the right …
WebFeb 2, 2024 · The converse bisector theorem of an angle states that if a triangle's interior point is equally spaced from its two sides, that point will be on the angle's bisector, which is the angle produced by the two line segments.

Therefore, the values of x and y are 140° and 40°, respectively. Example 3. The exterior angle of a triangle is 120°. Find the value of x if the opposite non-adjacent interior angles are (4x + 40) ° and 60°. Solution. Exterior angle = sum of two opposite non-adjacent interior angles. ⇒120° =4x + 40 + 60.
