AM MB and everything that is marked congruent.

What makes a triangle not congruent. Triangles with all three corresponding angles equal may not be congruent. But there are two triangles possible that have the same values so SSA is not sufficient to prove congruence. As shown in the figure below the size of two triangles can be different even if the three angles are congruent.

Preview this quiz on Quizizz. SSA Does not Work. The diagram shows the sequence of three rigid transformations used to map ABC onto ABC.

If two pairs of sides of two triangles are equal in length and the included angles are equal in measurement then the triangles are congruent. But if you click on Show other triangle you will see that there is another triangle that is not congruent but that still satisfies the SSA condition. In the figure above AC DF BC EF AD but ABC is not congruent to DEF.

They are not congruent because only one pair of corresponding sides is congruent. Remember that the included angle must be formed by the two sides for the triangles to be congruent. The triangles shown are congruent by the SSS congruence theorem.

State whether the two triangles are congruent. In other words similar triangles are the same shape but not necessarily the same size. This is not the case with D however as lengthshape of a triangle is changed and therefore it is not a congruent but a similar triangle.
