Question 6 - Angles - Chapter 2 Class 6 - Lines And Angles (Ganita Prakash)

Transcript

Question 6 Now mark any four points on your paper so that no three of them are on one line. Label them A, B, C, D. Draw all possible lines going through pairs of these points. How many lines do you get? Name them. How many angles can you name using A, B, C, D? Write them all down, and mark each of them with a curve as in Fig. 2.9.Drawing lines through pairs of points A, B, C, D Thus, we get lines (𝐴𝐵) ⃡ (𝐴𝐶) ⃡ (𝐴𝐷) ⃡ (𝐵𝐶) ⃡ (𝐵𝐷) ⃡ (𝐶𝐷) ⃡ Thus, we get total 6 lines Naming angles using A, B, C, D At Vertex A: ∠BAC ∠CAD ∠DAB At Vertex B: ∠ABC ∠CBD ∠DBA At Vertex C: ∠ACD ∠DCB ∠BCA At Vertex D: ∠ADC ∠ADB ∠CDB
