KEY KNOWLEDGE MATHS
Y7 Angles Protractors are tools used to measure angles with in degrees.

Estimate is a rough calculation of a number or quantity. It is not exact.

Acute angles measure more than 0° and less than 90°.

Obtuse angles measure more than 90° and less than 180°.

Reflex angles measure more than 180° and less than 360°. Angles around a point Vertically opposite angles Angles on a straight line Angles in a triangle Types of Triangles Angle Notation Exterior angles are angles outside of a shape. Interior angles are angles inside of a shape. Worked Example: < BCD or ‘x’ = 135°<br>
