![]() Polygon: A polygon is a 2D shape with straight sides. Kite: A quadrilateral with two pairs of sides that are same length. One pair of diagonally opposite sides is equal. Parallelogram: A quadrilateral with both pairs of opposite sides parallel and both pairs an equal length. Trapezium: A quadrilateral with one pair of parallel sides. (Differs from a square in that angles are NOT 90˚). Rhombus: A quadrilateral with both pairs or opposite sides parallel and all sides equal length. Right-angled triangle: A triangle that has a right angle. Scalene triangle: A triangle with 3 sides that are all unequal. Isosceles triangle: A triangle with 2 equal sides. illustrate and name parts of circles, including radius, diameter and circumference, and know that diameter is twice the radiusĮquilateral triangle: A triangle with 3 equal sides and 3 equal angles.find unknown angles in triangles, quadrilaterals and regular polygons.recognise, describe and build simple 3D shapes, including making nets.draw 2D shapes using given dimensions and angles.classify 2D and 3D shapes by talking about parallel and perpendicular edges and faces.distinguish between regular and irregular polygons.find missing lengths and angles of rectangles.estimate and compare acute, obtuse and reflex angles.identify 3D shapes from 2D representations.identify lines of symmetry in 2D shapes.identify acute and obtuse angles and compare and order angles.compare quadrilaterals and triangles, based on their properties and sizes.identify horizontal and vertical lines and pairs of perpendicular and parallel lines.identify right angles and know that two make a half-turn, three make a three-quarter turn and four a complete turn.understand that a right angle is a quarter turn and know whether the turn is clockwise or anti-clockwise.compare and sort common 2D and 3D shapes.identify 2D shapes on the surface of 3D shapes.identify and describe 3D shapes, including the number of edges, vertices and faces.identify and describe the properties of 2D shapes, including the symmetry and line symmetry.sort, make and describe common 2D and 3D shapes.3D shapes including cubes, cuboids, pyramids and spheres.2D shapes including rectangles, squares, circle and triangles.In Year 1, children need to be able to recognise and name: Children are expected to be able to name these shapes, and also discuss the properties of these shapes. Teachers will often talk about the fact that 2D shapes are 'flat' and 3D shapes are not. The first thing they need to learn is the difference between 2D and 3D shapes. You have these two faces that are circular and then they are opposite each other.Throughout their time at primary school, children will be taught about various 2D (two-dimensional) and 3D (three-dimensional) shapes. Thing that looks like a can is a cylinder. Which one is a sphere? When I think sphere, I think of a globe. Sometimes it'll be resting like this, sometimes it'll be on it's side, but this is a triangular prism. Have two opposite-facing sides that are triangles. In a square pyramid, theįaces which are triangles all meet at a point. This is actually what'sĬalled a triangular prism. You see this up here is a triangle and you see this down here is a triangle, although they're connectedīy these rectangular sides. In addition, geometric shapes can be divided into symmetrical and asymmetrical, as well as 2D and 3D. In this case, the number of points, the number of lines, and the angle measurement resulting from them are different for each geometric shape. If you look at this shape right over here, it has sides that are triangles. The number of points where geometric shapes meet and the number of lines that connect varies. Here is rectangular on every side, and it's three dimensions. That is rectangular, notice, this shape right Three-dimensional object, and since it's saying a rectangular prism, well, the best one here Which one is a rectangular prism? A prism you can view as a If it's a triangular pyramid, then the base would only have three sides, but this is a square pyramid. So the base of this right over here is a square. It a square pyramid is the idea that its base is a square. This shape here on the rightĬlearly looks like a pyramid, and the thing that makes ![]() Really, this is just something to know, because some people in various subjects will sometimes throw out these words. Answer: Some of the most common 2D shapes are triangle, square, rectangle, polygon, pentagon, hexagon, heptagon, octagon, nonagon, decagon, etc. Which one is a cylinder? Let's just work through this together. Which of these is a rectangular prism? Which one is a triangular prism? Which one is a sphere and What I want you to do is pause this video and think about which of these
