1 answer:
Answer:
Right Triangle.
Step-by-step explanation:
Given AB is a diameter of a circle O.
Point C is located on the circle's circumference as shown in the attached diagram.
The angle formed at C is the angle subtended by the diameter AB. Therefore, the angle at C is a Right Angle by the theorem stated below.
Theorem: Angle subtended by the diameter is a right angle.
This makes triangle ACB a Right Triangle.
