Activity -2 Sum of interior angles of quadrilateral is 360°

Hey!hello! Welcome back to Kidso'lab., learning by doing platform. Learn geometrical theory through art and craft . "Tell me and I forget.Teach me and I remember. Involve me and I learn " Benjamin Franklin Hope you all are doing well . First of all Thank you so much for your love ❤ and support 👭👫 . Now we have 600 in our Kidso'lab., family. It is possible only because of your support to my small channel. Once again thank you so much my lovely family . Music: Happy Summer Musician: ZakharValaha URL: https://pixabay.com/music/upbeat-happ... Let's learn today "Sum of interior angles of a quadrilateral is 360° by paper cutting and pasting method " . We need :- 1)Maths lab activity book 2)Colour paper 3)Colour pen 4)Black ⚗ and blue 💙 pen 5)Ruler 6)Gum 7) A pair of scissors✂ Procedure :- 1) Draw all possible kinds of quadrilaterals I.g Squares , Rectangle, parallelogram , rhombus , concave quadrilateral . 2) Name the 4 angles as 1,2,3 and 4 . 3) Colour all the 4 angles of each quadrilateral. 4) Using scissors cut the angles 5) Do the placement and paste them in the right place .Paste in such a way that there should be no gap in between them . All the vertices of 4 angles should coincide in the center. 6) Draw another rectangle and draw a diagonal in it. 7) paste them to form a rectangle. Observation :- 1)Observe all the figures . From figure 1,2,3,4,5, we observed that Angles (1+2+3+4)=360° or a complete angle Which proved that "Sum of the interior angles of quadrilateral is 360°". 2) From the last figure ,we observe that ∆1 +∆2=180°+180° = 360° As sum of the interior angles of triangle is 180°. Complimentary activity:- Angle sum property of a triangle. Take a triangle .Name their angles as 1,2, and 3 Colour them . Cut them . Paste them in such a way that ,there should be no gap in between them . What do you observe ?? (1+2+3)=180° They all lie in a straight line . Thank you 🙏So much to watch 👀 the video till the end 🔚.
