GEOMETRY 

You should be able to

 

 explain concepts relating to geometry;

 

Point, line, parallel lines, intersecting lines and perpendicular lines, line segment, ray, curve, plane, angle (acute, obtuse, reflex, right angle, straight angle), face, edge, vertex.

 

 draw and measure angles and line segments accurately using appropriate geometrical instruments;

 

 

 construct lines, angles, and polygons using appropriate geometrical instruments;

 

Parallel and perpendicular lines. Triangles, quadrilaterals, regular and irregular polygons. Angles to be constructed include 30, 45, 60, 90, 120.

 

 identify the type(s) of symmetry possessed by a given plane figure;

 

Line(s) of symmetry, rotational symmetry, order of rotational symmetry.

 

 solve geometric problems using properties of:

 

(a) lines, angles, and polygons;

Vertically opposite angles, alternate angles, adjacent angles, corresponding angles, co-interior angles, angles at a point, complementary angles, supplementary angles. Parallel lines and transversals. Equilateral, right, and isosceles triangles. Square, rectangle, rhombus, kite, parallelogram, trapezium.

Prisms, pyramids, cylinders, cones, sphere.
