Well! The reasons can be anything, but the students have to submit a polished paper on time anyhow. If you have the circle theorem assignment and are worried about how to solve the circle theorem questions without any mistake, then this blog can prove helpful. Before you jump to solve the questions, must know some terms related to the circle theorem. Move ahead to know them!
Formula:r= c/2π
Formula: d=2r
Formula:Length of chord = 2√ (r^{2}– d^{2})
Formula:Area of a Segment in Radians A = (½) × r^{2}(θ – Sin θ)
Formula:C= 2πr
Formula: Y=m x+c
Formula:Arc length = 2πr (θ/360)
Formula:Area of sector = (θ/360°) × πr^{2}
Angles Formed at the Centre and Circumference
Explanation: An angle at the center is always twice the angle at the circumference. CAB= 2CDB.
Angle in a Semicircle
Explanation: Angle in a semicircle is the right angle. Here, APB is 90°.
Angles in the Same Segment
Explanation: Angles in the same segment are always equal. In this diagram, BCE=BDE
Angles in a Cyclic Quadrilateral
Explanation: Opposite angles in a cyclic quadrilateral add up to 180°. Here, CFE+CDE= 180°.
Length of Tangents
Explanation: >The length of the two tangents is equal in a circle if they are drawn from one point of the circle. Here, DC = EC.
Angle Between Circle Tangent and Radius
Explanation: The angle between a tangent and a radius in a circle is the right angle. Hence, ODC= 90° and OEC= 90°.
Alternate Segment Theorem
Explanation: The angle between tangent and chord on the point (here, D) is equal to the angle in the alternate segment. As a result, ABC=CAP.
The Perpendicular from the Centre of the Circle Bisects the Chord
Explanation: Perpendicular line from the center (O) cuts the chord (CD) at the center. So, the perpendicular from the center bisects the chord. So, DBO = 90° and CBO = 90°.
Question 1. ABC are the points on the circumference, and O is the center of the circle. Angle A = 29°. You have to find the value of angle B.
Question 2. A, B, and C are the points on the circumference of the circle, and O is the center point of the circle. Angle AOB is 112°. You have to find the size of angle ACB.
Question 3. A, B, C, and D are the three points on the circumference of the circle. On the basis of this, answer the below two questions.
Question 4. Provide the answer to the below questions.
(a) Calculate the size of angle x.
(b) Support the answer with a reason.
Question 5. A, B, C, and D are three points on the circumference of a circle, and the center is O; AC is a diameter.
Angle ABD = 58°
Angle CDB = 22°
You have to find the sizes of angle ACD and ACB, with reasons for your answers.
These all 5 questions are vital. So read them effectively and then try to find their answers. You can find out the answers quickly if you know the circle theorem rules. UK students have to solve these types of questions in their assignments. Often, you have to prove the answer with reasons. GCSE students also have to solve circle theorem questions in their maths papers.
