Circle theorems summary sheet
WebThe graphic above shows 6 circle theorems. 1) The angle at the center is twice the angle at the circumference. 2) Angles in the same segment are equal. 3) Opposite angles in a cyclic quadrilateral are equal. 4) The angle in a semi-circle is always 90°. 5) The alternate angle theorem. 6) The angle between the tangent and the radius is always 90°. WebThese sheets contain sketches of circle theorems and blanks for the students to fill in in their own words. They can then use the notes in a future lesson to fill in the blanks on the ‘Fill In The Blanks’ sheet. The idea was to save them drawing poor sketches in their books and to write the rules in their own words.

WebThe first circle theorem we’re going to use here is: Rule 3, the angle at the centre is twice the angle at the circumference. \angle BAD = 126\degree \div 2 = 63\degree ∠B AD = 126° ÷ 2 = 63°. Since the angles in a quadrilateral sum to \textcolor {orange} {360\degree} 360°, we can find the angle we’re looking for.
WebCircle theorems are properties that show relationships between angles within the geometry of a circle. We can use these theorems along with prior knowledge of other angle properties to calculate missing angles, … WebFeb 8, 2024 · Chord-chord power theorem: When two chords of a circle intersect, the product of the parts of one chord is equal to the product of the parts of the other chord. Tangent-secant power theorem: When a tangent and a secant of a circle meet at an external point, the measure of the tangent squared is equal to the product of the secant’s …
WebThese are the circle theorems you need to know: Proof: Note: Once you have proved a theorem, you don’t need to prove it again if you need to use it to prove another theorem. The angle subtended at the centre of a circle is double the angle subtended at the circumference Angle AOC is double angle ABC 𝑥 2𝑥 C B O A ∴ B A C O WebSo this arc length is going to be 135/360 of the entire circumference, so times six pi, six pi inches. So let's see if we can simplify this a little bit. So let's see, we could divide the …
