Pupil outcome: I can construct a logical argument. Key learning points: - A logical argument does not have to only be algebraic. - Geometrical reasoning can be used to argue that something is true. - Values can be used to demonstrate...

Pupil outcome: I can appreciate and use the criteria by which triangles are congruent (ASA and AAS). Key learning points: - By knowing two angles and a length in the triangle and image, you can prove congruence. - The angle pairs must be...

Pupil outcome: I can appreciate and use the criteria by which triangles are congruent (SAS). Key learning points: - By knowing two side lengths and the angle between them in the triangle and image, you can prove congruence. - The angle...

Pupil outcome: I can recognise that for congruent shapes both side lengths and angle sizes are preserved. Key learning points: - Two shapes are not congruent if there is a pair of lengths with a scalar not equal to one. - Congruent does...

Pupil outcome: I can identify a shape from its properties and state the properties of a given shape.

Key learning po
ints:
- Many shapes have similar p
roperties.
- It is not always clear which shape is being described so...

Pupil outcome: I can use the fact that the interior angles of any triangle sum to 180° to find the size of missing angles. Key learning points: - Missing angles in triangles can be found using the angle sum. - Missing angles in triangles...

Pupil outcome: I can appreciate what constitutes the proof of a statement and what is required to disprove. Key learning points: - Substituting values can reveal whether the conjecture is wrong. - This is referred to as disproving. - A...

Pupil outcome: I can find the interior angle of any regular polygon or deduce the interior angle of an irregular polygon. Key learning points: - Any polygon can be split into triangles. - Using these triangles you can demonstrate the...

Pupil outcome: I can recognise that a pair of parallel lines traversed by a straight line produces supplementary co-interior angles. Key learning points: - Co-interior angles can be identified in an arrangement of 3 line segments. - If...

Pupil outcome: I can solve problems that require a combination of angles facts to identify values of missing angles, providing explanations of reasoning and logic used. Key learning points: - Missing angles can be found using parallel...

In this video, we solve problems using the relationship between inscribed angles, central angles, and arcs (in circles).
