2D Shapes How many different triangles can you make on the grid? Don’t include reflections / rotations of triangles already made How many different squares.
A parallelogram has opposite sides and opposite angles equal.
Shapes and their properties. What am I? I have 2 pairs of equal sides I have 2 pairs of parallel sides I have 0 lines of symmetry I have no right-angles.
Objective: Pupils can name 2D shapes Rectangle Square Oblong Name this shape.
A. Slack. A parallelogram has opposite sides and opposite angles equal.
Rotational Symmetry All 2 dimensional shapes have some rotational symmetry. The degree of rotational symmetry that an object has is known as its order.
Parallel lines are always the same distance apart They go in the same direction They never meet.
Let’s review our shapes….
All about Shapes Ask Boffin!.
What 2D shape am I?.
Reflectional Symmetry The image is exactly the same on both sides… therefore it is reflected across the line of symmetry. WARM UP: Draw lines of Symmetry.
Naming shapes. Shape names you should know…. Triangles Right angled Scalene – no sides the same length. Isosceles – 2 sides and 2 angles equal. Equilateral.
Name the Shape circle square rectangle triangle hexagon octagon
Geometry Quadrilaterals. Geometry: Plane Shapes quadrilateral: any closed, four-sided shape.
No rotational Symmetry Order 4 Order 3 Order 2 Order 5 Order 6 Order 3 Order 5.
J.Byrne Types of Triangles pg 1 The sum of the angles in any triangle is 180° Equilateral Triangle 3 sides and 3 angles are equal Isosceles.
Circle – Formulas Radius of the circle is generally denoted by letter R. Diameter of the circle D = 2 × R Circumference of the circle C = 2 × × R (

© T Madas. 1.Angles in a straight line add up to 180° 2.The diagonals of a rhombus meet at right angles 3.Two right angles make up a full turn 4.Perpendicular.
QUADRILATERALS. A plane shape with four straight sides is called a quadrilateral. We name quadrilaterals by looking at the properties of their sides.
Our learning objectives today: To be able to recognise and name 2D shapes. To know about quadrilaterals.

Polygons Lesson What is a polygon? A polygon is a simple, closed, two-dimensional figure formed by three or more line segments (sides). Closed?
Shape and Space (Quadrilaterals) By Ivy Law 4A(21) & Joanne Ho 4A(11)
Hexagons have 6 sides and 6 angles and vertices.
Quadrilaterals Jacob, Allie, and Jesenia. Definition ★ Quadrilateral means “4 sides ★ “Quad” means 4 and “lateral” means sides.
