Question

1. In circle O, diameter AB has been drawn, Locate point C anywhere between A and B (on either side of the

diameter). Draw in
AC
What type of triangle is AACB ? Exp
and BC

Answer 1

Right Triangle.

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.
