Analyze the diagram below and complete the instructions that follow. is an isosceles triangle with base . Determine whether by the HL theorem. Explain your reasoning. The diagram is not to scale. A. 1) , given 2) , definition of an isosceles triangle 3) by the HL theorem B. 1) , given 2) , definition of an isosceles triangle 3) , all right angles are congruent 4) by the HL theorem C. 1) , given 2) , definition of an isosceles triangle D. The triangles are not right triangles, so the HL theorem cannot be used to prove congruence. Please select the best answer from the choices provided
