can some one send the sure questions from lines and angles ,polynomials,coordinate geometry grade 9 that will come in exam
Answers
Answer:
POLYNOMIALS:
Definition of a polynomial in one variable, with examples and counter examples. Coefficients of a
polynomial, terms of a polynomial and zero polynomial. Degree of a polynomial. Constant, linear, quadratic
and cubic polynomials. Monomials, binomials, trinomials. Factors and multiples. Zeros of a polynomial.
Motivate and State the Remainder Theorem with examples. Statement and proof of the Factor Theorem.
Factorization of ax + bx + c, a ≠ 0 where a, b and c are real numbers, and of cubic polynomials using the
Factor Theorem.
Recall of algebraic expressions and identities.
factorization of polynomials
CO-ORDINATE GEOMETRY
The Cartesian plane, coordinates of a point, names and terms associated with the coordinate plane,
notations, plotting points in the plane.
LINES AND ANGLES:
(Motivate) If a ray stands on a line, then the sum of the two adjacent angles so formed is 180° and the
converse.
2. (Prove) If two lines intersect, vertically opposite angles are equal.
3. (Motivate) Results on corresponding angles, alternate angles, interior angles when a transversal
intersects two parallel lines.
4. (Motivate) Lines which are parallel to a given line are parallel.
5. (Prove) The sum of the angles of a triangle is 180°.
6. (Motivate) If a side of a triangle is produced, the exterior angle so formed is equal to the sum of the two
interior opposite angles.
