15. Think About a Plan You and a friend are cutting triangles out of felt for an art project. You want all the triangles to be congruent. Your friend tells you that each triangle should have two 5-in. sides and a 40° angle. If you follow this rule, will all your felt triangles be congruent? Explain. How can you use diagrams to help you? • Which postulate, SSS or SAS, are you likely to apply to the given situation?
