Sagot :
Answer:
HL, SAS, ans SSS
Step-by-step explanation:
ASA and AAS cannot be used because we can only confirm one angle of each triangle.
Congruent shapes have equal corresponding sides and angles.
The congruence theorems that can be used to prove [tex]\triangle ABR \cong \triangle ACR[/tex] are HL, SAS, and SSS
[tex]\triangle ABR \cong \triangle ACR[/tex] means that, the triangles are congruent.
From the attached figure, we have the following congruent sides and angle:
- AB and AC --- Side
- BR and CR --- Side
- AR and AR --- Side (Hypotenuse Leg)
- Angle C and Angle B --- angle
The above highlights mean that the following theorems can be used to prove that the triangles are congruent:
HL, SAS, and SSS
