Answer:
1. (Box on the left): Given.
2. (Box on the right): Angle Addition Postulate.
3. °+°=∠DEF
4. Definition of right triangle.
5. ∠DEF is a right triangle.
Step-by-step explanation:
1. You have the angles given in the first figure.
2 and 3. The Angle Addition Postulate establishes that if GE is in the interior of the angle ∠DEF, then:
°+°=∠DEF
4. A rigth triangle is a triangle that has a angle of 90 degrees.
5. The angle ∠DEF measures 90 degrees, therefore, the triangle is a right triangle.
