The statement triangle BCD is a right angle triangle because an angle in a semicircle is a right angle option 1 is correct.
<h3>What is a circle?</h3>
It is defined as the combination of points that, and every point has an equal distance from a fixed point (called the center of a circle).
We have a diagram shown in the picture.
BC is the diameter of the circle.
Point B and Point C lies on the circle.
If a point D, which is unique from points B and C, is plotted on circle A.
Then the right angle triangle will be formed because an angle in a semicircle is a right angle.
Thus, the statement triangle BCD is a right angle triangle because an angle in a semicircle is a right angle option 1 is correct.
