**Geometry and Measures:F**

**1. Use conventional terms and notations:**

- points, lines, vertices, edges, planes
- parallel lines, perpendicular lines, right angles
- polygons, regular polygons and polygons with reflection and/or rotation symmetries
- use the standard conventions for labelling and referring to the sides and angles of triangles
- draw diagrams from written description

**2. Use the standard ruler and compass constructions**

- perpendicular bisector of a line segment
- constructing a perpendicular to a given line from/at a given point
- bisecting a given angle)
- use these to construct given figures and solve loci problems
- know that the perpendicular distance from a point to a line is the shortest distance to the line

**3. Angles**:

- Apply the properties of angles at a point
- at a point on a straight line
- vertically opposite angles
- alternate and corresponding angles on parallel lines
- derive and use the sum of angles in a triangle

**4. Derive and apply the properties and definitions of:**

- special types of quadrilaterals, including square, rectangle, parallelogram, trapezium, kite and rhombus;
- triangles and other plane figures using appropriate language

**5. Use the basic congruence criteria for triangles (SSS, SAS, ASA, RHS)**
