Lesson-4.1.15- alculate unknown angles and give explanations using the following geometrical properties of circles: ??? angle in a semicircle = 90?? ??? angle between tangent and radius = 90?? ??? angle at the centre is twice the angle at the circumference ??? angles in the same segment are equal ??? opposite angles of a cyclic quadrilateral sum to 180?? (supplementary) ??? alternate segment theorem.PreviousLesson-5.1.1- Use metric units of mass, length, area, volume and capacity in practical situations and convert quantities into larger or smaller units. Units include: ??? mm, cm, m, km ??? mm^2 , cm^2 , m^2 , km^2 ??? mm^3 , cm^3 , m^3 ??? ml, l ??? g, kg .Next
