QUESTION TWO
Below is a circle with centre .
is a diameter of the circle, is a point on the circumference.
What is the size of angle?
Answers
is a diameter of the circle, we know that triangle is confined within the semi-circle.
So we can say that the angle in a semi-circle is a right-angle to deduce that .
To find , we just need to subtract from 180°

QUESTION THREE
Below is a circle with centre .
, and are points on the circumference.
Angle is 126°and angle is .
Find angle .
You must show your workings.
Answer
The angle at the centre is , so;
.
We now know two out of the four angles inside .
To find a third, simply observe that angles around a point sum to :
Since the angles in a quadrilateral sum to , we can find the angle we’re looking for.
