Do-Now Find the value of x. 5x – 4 4x + 14 100º Find x given that the perimeter is 56. 4x – 18 x2 – 6x 20 – x Congruent Triangles SSS – Side Side Side SAS – Side Angle Side *if three sides of one triangle are congruent to three sides of another triangle, then they are congruent. *if two sides and the angle between them are congruent to another triangle, then the triangles are congruent. ASA – Angle Side Angle *if two angles and the side between them are congruent to another triangle, then the triangles are congruent. AAS – Angle Angle Side *if two angles and the non-included side are congruent to another triangle, then the triangles are congruent. HL – Hypotenuse Leg *if the hypotenuse and a leg are congruent to the hypotenuse and a leg of another triangle, then the triangles are congruent. CPCTC – Corresponding Parts of Congruent Triangles are Congruent
