When the third angle is 90 degree, it is called a right isosceles triangle. 48 (1975), p. 198).Let us consider two congruent squares. In some cases, we are allowed to say that two triangles are congruent if a certain 3 parts match because the other 3 MUST be the same because of it. <>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> 3 0 obj The following example requires that you use the SAS property to prove that a triangle is congruent. ∣ x + 3 ∣∣ x − 3 ∣≤ ( ∣ x − 3 ∣ + 6) ∣ x − 3 ∣< ( δ + 6) δ.
