WebGCSE Edexcel Vectors A vector quantity has both size and direction. Vectors can be added, subtracted and multiplied by a scalar. Geometrical problems can be solved using vectors. Part of... WebYou need to be able to use the basic conversions. 1 cm 2 = 10 2 mm 2 = 100 mm 2. 1 m 2 = 100 2 cm 2 = 10 000 cm 2. 1 km 2 = 1000 2 m 2 = 1 000 000 m 2. There are also less common conversions. 1 hectare (ha) = 10 000 m 2. If you are given an imperial conversion (such as miles to kilometres) for lengths: Write the conversion as a ratio.

Circle theorem - Wikipedia

WebOur first circle theorem here will be: tangents to a circle from the same point are equal, which in this case tells us that AB and BD are equal in length. This means that ABD must … WebSpecification notes. G10. Apply and prove the standard circle theorems concerning angles, radii, tangents and chords and use them to prove related results. including. angle at centre is equal to twice angle at circumference; angle in a semi-circle is 90°; angles in the same segment are equal; opposite angles in a cyclic quadrilateral sum to 180°; diana fosha books

Webproofs were attempted but in this question where marks were awarded for Quality of Written Communication, it was essential that theorems were quoted accurately using correct mathematical language. Q9. There were some excellent solutions to this question showing an accurately constructed circle followed by WebA combination of a 180° rotation about a centre and an enlargement of scale factor k about the same centre is the same as a single enlargement. This enlargement would have the same centre but the scale factor would be -k. The order of the combination can be important to the overall effect. A reflection in the line y = x followed by a ...
