Five geometric theorems
WebSep 12, 2024 · This “triangle” has an angle sum of 90+90+50=230 degrees! Figure 9.5. 1: On a sphere, the sum of the angles of a triangle is not equal to 180°. The surface of a sphere is not a Euclidean plane, but locally the laws of the Euclidean geometry are good approximations. In a small triangle on the face of the earth, the sum of the angles is very ... If in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio and hence the two triangles are similar. Let ∆ABC and ∆PQR are two triangles. Then as per the theorem, AB/PQ = BC/QR = AC/PR (If ∠A = ∠P, ∠B = ∠Q and ∠C = ∠R) And ∆ABC ~ ∆PQR See more In any triangle, the sum of the three interior angles is 180°.
