Angle Inscrbed Ina Semicircle Is A Right Angle
The angle at vertex C is always a right angle of 90 and therefore the inscribed triangle is always a right angled triangle providing points A and B are across the diameter of the circle. An Inscribed Angle Has The Same Measure As The Arc It Subtends.

Angle inscrbed ina semicircle is a right angle . Experts are tested by Chegg as specialists in their subject area. The angle inscribed in a semicircle is always a right angle 90. The area within the triangle varies with respect to its perpendicular height from the base AB. A circle measures 360 degrees so a semicircle measures 180 degrees. An inscribed angle is equal to half the measure of the intercepted arc. For example an inscribed angle which is a right angle intercepts a 180 degrees arc. In the diagram above AB is the diameter of a circle that divides t
