Curriculum Prioritisation for Primary Maths These materials heavily reflect the prioritisation approach of the readytoprogress criteria in the DfE Primary Mathematics Guidance 2020 and on the . Terra Alta/East Preston . School. Geometry Unit. Ray. Ray. --part of a line that has one. endpoint and goes on endlessly. in the other direction.. Congruent. Equal in size and shape.. Degrees. The unit used to. Angles are ACUTE angles Angles equal to 90 are RIGHT angles Angle are OBTUSE angles Angles equal to 180 Angles more than 180 are REFLEX angles ANGLES RULES Angles about a point add to 360 Essential Question. How can you describe angle pair relationships and use thee descriptions to find angle measures?. Objectives. Identify complementary and supplementary angles. Identify linear pairs and vertical angles. Geometric Reasoning. Dr J Frost (jfrost@tiffin.kingston.sch.uk) . Last modified: 12. th. April 2014. Objectives: . Be able to reason about sides and angles, and find interior/exterior angles of polygons.. Identifying, Describing, and Applying Theorems about Circles. Understand and apply theorems about circles. G-C.2, Identify and describe relationships among inscribed angles, radii, and chords. . Include the relationship between central, inscribed, and circumscribed angles; inscribed angles on a diameter are right angles; the radius of a circle is perpendicular to the tangent where the radius intersects the circle.. Protractor: . What do you notice? . Task One: . Look at the protractor. Write down everything that you notice about the protractor. Try and come up with at least . 10 facts. Think about . number patterns . 1. Recall: We’ve defined the sine function in two ways. :. . and. ..  . 2. All the trig functions can also be defined in terms of the . unit circle. (circle with radius 1, centered at the origin. Unit Outline. 6-1 The Polygon Angle-Sum Theorems. 6-2 Properties of Parallelograms. 6-3 Proving that a Quadrilateral is a Parallelogram. 6-4 Properties of Rhombuses, Rectangles and Squares. 6-5 Conditions for Rhombuses, Rectangles and Squares. Unit 3: This unit Introduces Transversals, and angles based on transversals, including corresponding angles, Same Side Interior Angles, Alternate Exterior and Alternate Interior Angles, and the unique properties of Perpendicular Transversals. . This unit introduces Polygons. . It defines polygons and regular polygons, and has the Polygon Angle Sum theorem. . This unit also details quadrilaterals, special quadrilaterals, congruent polygons, similar polygons, and the Golden Ratio.. The vertical distance from rotary table to Point B is called a true vertical depth. The inclination angle ‘I’ is the angle between vertical and the wellbore. . The direction angle ‘A’ is specified as the azimuth between the geographic north and the projection of a wellbore on a horizontal plane.. 18. Horizontal. Going. left and right. 19. Vertical. Going up. and down. 20. Parallel. 2 lines. , equal distance apart that never intersect. 21. Perpendicular. 2 lines that meet at a 90. angle. 22.
